Yes. I'm afraid I've lost the thread a bit, but ISTR that was what we arrived at. Plus something had to be changed with regard to fflush at the end of the update (it was called too early, or too late).

I think we want to add begin/end_frame_update hooks, and we want them to send the escape sequences that are determined by some state variable which tells us which of the 2 protocols to use. We then need a function to allow changing that state variable, perhaps by an explicit user command. Bonus points for making the state variable be terminal-specific, so that the same Emacs session could have TTY frames on several different types of terminal, and use the correct protocol for each one of them. I hope I explained this well enough; if not, feel free to ask specific questions. > Alternatively, we can allow users to specify it as a terminal capability and let them override it. Like, `(setq > xterm-extra-capabilities (quote (modifyOtherKeys setSelection)))` No, that's too dangerous, and not really needed. It's not like there are many different protocols for synchronized update. Thanks.

But could you please elaborate a bit more on what I can do now? Do we want to add a hook like `begin_frame_update` or we need to add a `sync_update_begin_escape_code` or we just say, sync_update_protocol (we have 2 of those now). Alternatively, we can allow users to specify it as a terminal capability and let them override it. Like, `(setq xterm-extra-capabilities (quote (modifyOtherKeys setSelection)))` Which way would we like to proceed?

Here's some code how tmux works with that [1], we can probably avoid it by providing a frame-local flag which enables the functionality, so that multiple emacs clients might be connected from potentially different terminals. We can improve the default value of the flag based on terminal capabilities later once we have confidence in the way it works and probably extend it to support different specifications of syncing.

I guess by P1 you mean these two sequences: BSU: ESC P = 1 s ESC \ ESU: ESC P = 2 s ESC \ whereas by P2 you mean these: DECRQM: ESC [ ? 2026 $ p DECRPM: ESC [ ? 2026 ; n $ y (with n = 0..4, and 0 or 4 means "no support") BSU: ESC [ ? 2026 h ESU: ESC [ ? 2026 l > > Do you happen to know where is the definitive documentation of Sync? > > Sorry, I don't know a definitive documentation. And any documentation at all? Anyway, given the problems usually related to querying terminals about potentially unsupported features, and the general mess in this field, I think our best bet is to have a function that could switch the frame-update hooks between these 3 states: . unused . used with P1 BSU/ESU sequences . used with P2 BSU/ESU sequences WDYT?

And somehow define what to send to the terminal, P1 or P2. I installed iTerm2 just now, which implements P2 at least. iTerm2 has a preference options to switch GPU acceleration on/off. iTerm2 uses TERM=xterm256-color, independent of the GPU setting. So matching TERM wouldn't work with iTerm2. The query control sequence of P2 seems to return if GPU accel is on or off on iTerm2. > >> >> BTW, tmux uses the sync update for their own TUI and they check "Sync" terminal capability.

I'd like to emphasize that this is not a problem limited to Alacritty. There are a number of terminal emulators with GPU accelleration, which all share the same cpmceptual problem. Alacritty is just the one with the best marketing, riding the Rust wave. AFAICT, we have the following situation: - We have two proposals P1 and P2 (that we know of). Alacritty implements P1 only, says Dmitrii, and P2 has a table of emulators implementing P2, which may or may not implement P1. - Neither P1 nor P2 are detectable as a terminfo capability, so one has to match TERM or use a boolean switch. I don't know if all emulators use a discernable TERM, or if they use standard TERM names. > >> BTW, tmux uses the sync update for their own TUI and they check "Sync" terminal capability.

It's a non-standard terminfo capability which is only shown with infocmp -x. Neither P1 nor P2 mention Sync in any way.

OK, thanks.
So now the next question is: on what should we base the activation of
these hooks? There are several alternatives:
. if alacritty produces a distinct value from tty-type, we could use
that, or
. if alacritty has a distinct terminfo capability that other
terminals don't, we could use that, or
. expose a variable to Lisp that users could set in order to turn
this on and off, and tell users to turn it on if they see the
issue
Any other ideas?
> BTW, tmux uses the sync update for their own TUI and they check "Sync" terminal capability. Do we need to

What is that Sync capability, what is its value for tmux, and how is
it supposed to be used? Is there any documentation I could read about
that?

I tried the patch (see attachments) and everything worked perfectly. No flickering. I tried to implement the second spec, but it didn't work (at least in Alacritty). But, I can try to add support for both. BTW, tmux uses the sync update for their own TUI and they check "Sync" terminal capability. Do we need to do the same or we can just send the escapes and hope the unsupported terminal would just recover? Side note: I still have the issue when I run emacs inside of tmux, but it is due to lack of support from tmux side. I created a bug and will try to implement the functionality in tmux sooner or later. See https://github.com/tmux/tmux/issues/3325 foe details. I assume, in the case of tmux, the multiplexer just consumes the escape codes and doesn't send them to the parent terminal.

Yes, BTW, I think I forgot to add the linke yesterday, there's also) a second specification here: https://gist.github.com/christianparpart/d8a62cc1ab659194337d73e399004036 This page looks relatively new, so maybe it's a newer version of the same proposal? I don't know how this all fits together. This one has also begin-update/end-update control sequences plus a query.

Actually, I think we'll need one more small change. These hooks are
called from update_begin and update_end like this:
/* Update the display. */
if (FRAME_INITIAL_P (f))
/* No actual display to update so the "update" is a nop and
obviously isn't interrupted by pending input. */
paused_p = false;
else
{
update_begin (f);
paused_p = update_frame_1 (f, force_p, inhibit_hairy_id_p, 1, false);
update_end (f);
}
if (FRAME_TERMCAP_P (f) || FRAME_MSDOS_P (f))
{
if (FRAME_TTY (f)->termscript)
fflush (FRAME_TTY (f)->termscript);
if (FRAME_TERMCAP_P (f))
fflush (FRAME_TTY (f)->output);
}
I think the fact that we call fflush (FRAME_TTY (f)->output) after
update_end is a conceptual bug, which only goes unnoticed because
update_end is a no-op on TTY frames. At least for the purpose of
testing the above possible fix, the order should be reversed: we
should fflush the terminal output _before_ we call update_end.

I had an idea: Until this all is standardized/stable, how about adding
two hooks that are called when Emacs is beginning a terminal update and
when it is done? The user could then send whatever he wants to the
terminal. Or maybe beginnign an update/end an update on any type of
frame even? Don't know if that's useful though.

Thanks.
So we have 2 alternatives:
. declare that flickering on alacritty is currently a known problem,
and wait till Someone comes up with the proper solution for Emacs;
. add that variable I mentioned above, and let users try to fix the
problem with alacritty by flipping it.
TBH, given your description, I'm no longer sure a simple boolean
variable that disables insert/delete-line optimization will do, since
the issue seems to be a much more general one. How sure are we that
some other scenario of redrawing a TTY frame won't cause similar
flickering regardless of the insert/delete-line feature? So maybe
just document the issue in PROBLEMS and advise against using
alacritty?

Unless some significant > new ideas or facts emerge in the next day or two, that is. I guess I've found these facts today, while rummaging in alacritty's Github project. Let me mention first that there's quite some flushing and flickering going on in alacritty's Github issues with all sorts of terminal applications (tmux, vim, neovim, ...), and on all platforms it runs on (MS-Windows, GNU/Linux, macOS, ...). Alacritty is one of a number of terminal emulators using OpenGL with GPU accelerated framebuffer display. I must admit that I didn't realize up to now that such a thing exists. Framebuffer updates depend on monitor refresh rates, among other things. One can only update at some given points in time (vsync, vblank, and so on, I'm not an expert). That's the typical N frames/second thing one can find in various contexts. (And note the different behavior Dmitrii mentioned on his second monitor.) Very simplified, what happens is that Alacritty seems to put framebuffer contents on the screen in the middle of updates sent from terminal clients. Which leads to flickering. For a longer story, see for instance https://github.com/karlstav/cava/issues/453 https://bytemeta.vip/repo/karlstav/cava/issues/453 https://github.com/alacritty/alacritty/issues/598 https://github.com/kovidgoyal/kitty/issues/4817 and also follow links there. One screencast there shows vim flickering in 100% the exact same way (even the colors) that Dmitrii showed with Emacs :-). The terminal emulators' proposed solution for this flickering seems to be that clients support "synchronized updates" as they call it. That is, a client sends the terminal emulator begin-update/end-update control sequences, which the emulator uses to avoid framebuffer updates in the middle of the update. Proposed specification: https://gitlab.com/gnachman/iterm2/-/wikis/synchronized-updates-spec A number of terminal clients seem to have added this. Tmux seems to do it. Vim I don't know but I'd wager it does when I see the screencast mentioned above and what Dmitrii showed. I think other applications do too, but I haven't digged deeper. I couldn't find information which terminfo capabilties are supposed to be used for this, and I don't think it's part of any official specification. And I'd like to add that alacritty.org says about itself "The software is considered to be at a beta level of readiness", so I'm a bit wary how stable this all is. In summary, this is for me a very likely candidate for "the root cause". Someone (tm) should probably take a deeper look at this. Maybe Dmitrii is up for it?

Probably, it is caused by slowness of SSH and/or and my misunderstanding of
the terminal capabilities, but I didn't see the problem when I was
connected to Linux using SSH.

It also might be caused by my limited knowledge of TTY. But, I see that we
redraw linest not from top to bottom, but actually we try to redraw
different portions of the screen at different times. (I am looking into
`do_scrolling`).
And my assumption is that we cleared some portion of the screen and
prepared it for new contents, but due to unsynced frame rates, the terminal
redraws that partial state. And only then, we add some content in those
empty lines and then the terminal redraws it again and we see what we
needed to see.
Do we always draw frame as a single atomic operation or those things aren't
synchronized at all?

I tried bigger/smaller and delete the condition completely, it didn't
help....

Also, I want to point out that `baud-rate` works and reduces part of the
flickering and improves the situation overall. but `tty->line_ins_del_ok =
0;` fixes it completely.
I can try to add a new variable to configure/override the behavior.

. Evening and weekend emails are a sign I allocated some regular working
hours for other things (such as family, gym, friends,...). And I encourage

That's a wrong conclusion, AFAIU. By "terminal or macOS problem" we
mean that some terminal commands, like those that insert and delete
lines in a region of a screen, cause flickering on those systems
and/or those terminals. That vim doesn't show this flickering tells
us nothing: it might well be that vim doesn't use these terminal
commands. After all, if we disable the use of those terminal commands
in Emacs, like you already tried, the flickering disappears. So by
the same logic we could conclude that there's no problem at all.

Why did you expect the problem to disappear when you use Emacs via SSH
on the same terminal? It's the same Emacs using the same algorithms
to decide which terminal commands to use in each case.

I don't see how this can happen. Emacs outputs commands basically one
after the other, so their execution should be at the terminal's speed.
However, there's one place where we accumulate bytes before flushing
them: in update_frame_1:
if (FRAME_TERMCAP_P (f))
{
/* Flush out every so many lines.
Also flush out if likely to have more than 1k buffered
otherwise. I'm told that some telnet connections get
really screwed by more than 1k output at once. */
FILE *display_output = FRAME_TTY (f)->output;
if (display_output)
{
ptrdiff_t outq = __fpending (display_output);
if (outq > 900
|| (outq > 20 && ((i - 1) % preempt_count == 0)))
fflush (display_output);
}
}
So maybe it's worthwhile to see if playing with the 900 figure here
helps in any way. Or maybe __fpending doesn't work well on macOS?

Given our inability to pinpoint the root cause of the problem, and the unsolved mystery why on some macOS systems the problem is much more prominent than on other macOS systems, I tend to introduce a variable that users could set from Lisp to tell Emacs not to use the optimized insert/delete-lines algorithm in scroll.c. Unless some significant new ideas or facts emerge in the next day or two, that is.

"Good news":
I've now installed Alacritty, and with this file
;; 57434.el
(setq display-line-numbers-type 'visual)
(global-display-line-numbers-mode)
(global-hl-line-mode)
(global-display-fill-column-indicator-mode)
and, in an alacritty terminal window
./emacs -nw -Q -l ../../57434.el xdisp.c
C-x 3
C-x o
C-x b *scratch* RET
C-x o
C-n/C-p
it sometimes flickers. A lot less than in your screencast showing emacs
-Q, but it's there.
The window of xdisp.c doesn't need to scroll for this to happen. It
suffices to hold C-n with key repeat, and then reverse to C-p with
repeat, and then C-n again, and so forth. I have to repeat that a dozen
times or so until it flickers. Key repeat is the maximum my system
allows (which is not very fast, TBH).
$TERM seems to be "alacritty" by default, which has different
capabilities than xterm-256color. But the flickering is also there with
xterm-256color.
And I double-checked with Terminal.app again: no flickering.

Flickering appears once there is some load on redrawing (line numbers, themes, lh mode, etc...). The line numbers expose that the most. Flickering region is always the same for the same cursor position. I previously messaged it in >>> Flickering is consistent for some specific area. If I scroll between 2 lines, back-and-forth Emacs flickers consistently. So, it flickers consistently at the same area and it correlates with the queue values (window, pos) in scroll.c when the const estimation decides to use insertion instead of writing. See scroll.c:do_direct_scrolling:697.

The new M1 Pro has some rendering optimizations, but I tried a different option and it didn't change anything.

The flickering isn't supposed to happen. Btw, can you figure out which screen lines flicker? Do all of them flicker, or just some? And if you disable relative line-numbers (i.e. use absolute line-numbers), do the lines still flicker? all of them? > E.g., Dmitrii, do you have some > display-related software/driver that has some "optimization" features > turned on? If so, can you turn them off and try again? Did you try looking for such features on your system?

Thanks.<br>
<br>
But I'm quite confused by all of this, because you don't show all t=
he<br>
relevant capabilities, AFAICT.<br>
<br>
We have in term.c:<br>
<br>
=C2=A0 tty->scroll_region_ok<br>
=C2=A0 =C2=A0 =3D (tty->Wcm->cm_abs<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0&& (tty->TS_set_window || tty->TS_=
set_scroll_region || tty->TS_set_scroll_region_1));<br>
<br>
=C2=A0 tty->line_ins_del_ok<br>
=C2=A0 =C2=A0 =3D (((tty->TS_ins_line || tty->TS_ins_multi_lines)<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 && (tty->TS_del_line || tty->TS_d=
el_multi_lines))<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0|| (tty->scroll_region_ok<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0&& tty->TS_fwd_scroll &=
amp;& tty->TS_rev_scroll));<br>
<br>
Please try all of the relevant capabilities and tell me which ones are<br>
supported and which aren't.=C2=A0 (Please also mention both the capabil=
ity<br>
string and its term.c flag name, so that I shouldn't need to jump<br>
back-and-forth in the source looking up each one to understand what it<br>
means.)<br>
<br>
Then we have in dispnew.c:<br>
<br>
=C2=A0 /* If we cannot insert/delete lines, it's no use trying it.=C2=
=A0 */<br>
=C2=A0 if (!FRAME_LINE_INS_DEL_OK (f))<br>
=C2=A0 =C2=A0 inhibit_id_p =3D 1;<br>
=C2=A0 [...]<br>
=C2=A0 /* Try doing i/d line, if not yet inhibited.=C2=A0 */<br>
=C2=A0 if (!inhibit_id_p && i < desired_matrix->nrows)<br>
=C2=A0 =C2=A0 force_p |=3D scrolling (f);<br>
<br>
Which means that 'scrolling', and thus 'scrolling_1' (where=
the<br>
problem happens) will not be called if the line_ins_del_ok flag is not<br>
set.<br>
<br>
Furthermore, we have in scrolling_1:<br>
<br>
=C2=A0 if (FRAME_SCROLL_REGION_OK (frame))<br>
=C2=A0 =C2=A0 {<br>
=C2=A0 =C2=A0 =C2=A0 calculate_direct_scrolling (frame, matrix, window_size=
,<br>

=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=
=A0 =C2=A0 =C2=A0 =C2=A0matrix, window_size, unchanged_at_top);<br>
=C2=A0 =C2=A0 }<br>
=C2=A0 else<br>
=C2=A0 =C2=A0 {<br>
=C2=A0 =C2=A0 =C2=A0 calculate_scrolling (frame, matrix, window_size, uncha=
nged_at_bottom,<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=

nged_at_top);<br>
=C2=A0 =C2=A0 }<br>
<br>
which means do_direct_scrolling (which causes the problem) will not be<br>
called if the terminal's scroll_region_ok flag is not set.<br>

`tty->TS_ins_line` (al) is supprted.
`tty->TS_ins_multi_lines` (AL) is supprted.
`tty->TS_del_line` (dl) is supprted.
`tty->TS_del_multi_lines` (DL) is supprted.
to verify that I used `tput <cap_name>`.
I think, that is sufficient for `tty->line_ins_del_ok` to be true, but fo
completeness:
`tty->TS_fwd_scroll` (sf) is supprted.
`tty->TS_rev_scroll` (sr) is supprted.
`tty->TS_set_window` (wi) is NOT supprted.
`tty->TS_set_scroll_region` (cs) is supprted.
`tty->TS_set_scroll_region_1` (cS) is NOT supprted.
BUt I do not know how to verify `tty->Wcm->cm_abs`.
```
tty->scroll_region_ok
=3D (tty->Wcm->cm_abs
&& (tty->TS_set_window || tty->TS_set_scroll_region ||
tty->TS_set_scroll_region_1));
```
```
tty->line_ins_del_ok
=3D (((tty->TS_ins_line || tty->TS_ins_multi_lines)
&& (tty->TS_del_line || tty->TS_del_multi_lines))
|| (tty->scroll_region_ok
&& tty->TS_fwd_scroll && tty->TS_rev_scroll));
```
BTW, here's a video with what I have with "-Q", it still flickers:

*If you get an email from me outside of the 9-5 it is *not* because I'm

flexibility

Thanks.<br>
<br>
But I'm quite confused by all of this, because you don't show all t=
he<br>
relevant capabilities, AFAICT.<br>
<br>
We have in term.c:<br>
<br>
=C2=A0 tty->scroll_region_ok<br>
=C2=A0 =C2=A0 =3D (tty->Wcm->cm_abs<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0&& (tty->TS_set_window || tty->TS_=
set_scroll_region || tty->TS_set_scroll_region_1));<br>
<br>
=C2=A0 tty->line_ins_del_ok<br>
=C2=A0 =C2=A0 =3D (((tty->TS_ins_line || tty->TS_ins_multi_lines)<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 && (tty->TS_del_line || tty->TS_d=
el_multi_lines))<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0|| (tty->scroll_region_ok<br>
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0&& tty->TS_fwd_scroll &=
amp;& tty->TS_rev_scroll));<br>
<br>
Please try all of the relevant capabilities and tell me which ones are<br>
supported and which aren't.=C2=A0 (Please also mention both the capabil=
ity<br>
string and its term.c flag name, so that I shouldn't need to jump<br>
back-and-forth in the source looking up each one to understand what it<br>
means.)<br>
<br>
Then we have in dispnew.c:<br>
<br>
=C2=A0 /* If we cannot insert/delete lines, it's no use trying it.=C2=
=A0 */<br>
=C2=A0 if (!FRAME_LINE_INS_DEL_OK (f))<br>
=C2=A0 =C2=A0 inhibit_id_p =3D 1;<br>
=C2=A0 [...]<br>
=C2=A0 /* Try doing i/d line, if not yet inhibited.=C2=A0 */<br>
=C2=A0 if (!inhibit_id_p && i < desired_matrix->nrows)<br>
=C2=A0 =C2=A0 force_p |=3D scrolling (f);<br>
<br>
Which means that 'scrolling', and thus 'scrolling_1' (where=
the<br>
problem happens) will not be called if the line_ins_del_ok flag is not<br>
set.<br>
<br>
Furthermore, we have in scrolling_1:<br>

<br>
which means do_direct_scrolling (which causes the problem) will not be<br>
called if the terminal's scroll_region_ok flag is not set.<br>
<br>
So given all of this, can you tell whether Emacs does TRT here?=C2=A0 That<=

=C2=A0 =C2=A0 setting these two flags?<br>
<br>
Assuming that Emacs does TRT, i.e. sets the flags correctly and uses<br>

*If you get an email from me outside of the 9-5 it is *not* because I'm
always on or expect an immediate response from you; it is because of work
flexibility
<http://www.inc.com/john-boitnott/how-flexible-hours-can-create-a-better-wo=
rk-life-balance.html>
. Evening and weekend emails are a sign I allocated some regular working
hours for other things (such as family, gym, friends,...). And I encourage
you to feel free to do the same.

Thanks.
But I'm quite confused by all of this, because you don't show all the
relevant capabilities, AFAICT.
We have in term.c:
tty->scroll_region_ok
= (tty->Wcm->cm_abs
&& (tty->TS_set_window || tty->TS_set_scroll_region || tty->TS_set_scroll_region_1));
tty->line_ins_del_ok
= (((tty->TS_ins_line || tty->TS_ins_multi_lines)
&& (tty->TS_del_line || tty->TS_del_multi_lines))
|| (tty->scroll_region_ok
&& tty->TS_fwd_scroll && tty->TS_rev_scroll));
Please try all of the relevant capabilities and tell me which ones are
supported and which aren't. (Please also mention both the capability
string and its term.c flag name, so that I shouldn't need to jump
back-and-forth in the source looking up each one to understand what it
means.)
Then we have in dispnew.c:
/* If we cannot insert/delete lines, it's no use trying it. */
if (!FRAME_LINE_INS_DEL_OK (f))
inhibit_id_p = 1;
[...]
/* Try doing i/d line, if not yet inhibited. */
if (!inhibit_id_p && i < desired_matrix->nrows)
force_p |= scrolling (f);
Which means that 'scrolling', and thus 'scrolling_1' (where the
problem happens) will not be called if the line_ins_del_ok flag is not
set.
Furthermore, we have in scrolling_1:
if (FRAME_SCROLL_REGION_OK (frame))
{
calculate_direct_scrolling (frame, matrix, window_size,
unchanged_at_bottom,
draw_cost, old_draw_cost,
old_hash, new_hash, free_at_end);
do_direct_scrolling (frame, frame->current_matrix,
matrix, window_size, unchanged_at_top);
}
else
{
calculate_scrolling (frame, matrix, window_size, unchanged_at_bottom,
draw_cost, old_hash, new_hash,
free_at_end);
do_scrolling (frame,
frame->current_matrix, matrix, window_size,
unchanged_at_top);
}
which means do_direct_scrolling (which causes the problem) will not be
called if the terminal's scroll_region_ok flag is not set.
So given all of this, can you tell whether Emacs does TRT here? That
is:
. are all the capabilities that are supposed to be available for
these two flags are indeed available?
. do we need to check any additional capabilities, which are in fact
used in the problematic scenario, but not tested as part of
setting these two flags?
Assuming that Emacs does TRT, i.e. sets the flags correctly and uses
only the capabilities that are conditions for the flags set, then the
next important question is: why doesn't Gerd see the flickering on a
very similar system and the same terminal emulator? Is it possible
that some other local software configuration on Dmitrii's machine
causes this, directly or indirectly? E.g., Dmitrii, do you have some
display-related software/driver that has some "optimization" features
turned on? If so, can you turn them off and try again?
Thanks.

Emacs is supposed to use the alternative capabilities, as follows from the condition for line_ins_del_ok flag to be set. Does it indeed use the other alternatives?

Thanks.
But I'm quite confused by all of this, because you don't show all the
relevant capabilities, AFAICT.
We have in term.c:
tty->scroll_region_ok
= (tty->Wcm->cm_abs
&& (tty->TS_set_window || tty->TS_set_scroll_region || tty->TS_set_scroll_region_1));
tty->line_ins_del_ok
= (((tty->TS_ins_line || tty->TS_ins_multi_lines)
&& (tty->TS_del_line || tty->TS_del_multi_lines))
|| (tty->scroll_region_ok
&& tty->TS_fwd_scroll && tty->TS_rev_scroll));
Please try all of the relevant capabilities and tell me which ones are
supported and which aren't. (Please also mention both the capability
string and its term.c flag name, so that I shouldn't need to jump
back-and-forth in the source looking up each one to understand what it
means.)
Then we have in dispnew.c:
/* If we cannot insert/delete lines, it's no use trying it. */
if (!FRAME_LINE_INS_DEL_OK (f))
inhibit_id_p = 1;
[...]
/* Try doing i/d line, if not yet inhibited. */
if (!inhibit_id_p && i < desired_matrix->nrows)
force_p |= scrolling (f);
Which means that 'scrolling', and thus 'scrolling_1' (where the
problem happens) will not be called if the line_ins_del_ok flag is not
set.
Furthermore, we have in scrolling_1:
if (FRAME_SCROLL_REGION_OK (frame))
{
calculate_direct_scrolling (frame, matrix, window_size,
unchanged_at_bottom,
draw_cost, old_draw_cost,
old_hash, new_hash, free_at_end);
do_direct_scrolling (frame, frame->current_matrix,
matrix, window_size, unchanged_at_top);
}
else
{
calculate_scrolling (frame, matrix, window_size, unchanged_at_bottom,
draw_cost, old_hash, new_hash,
free_at_end);
do_scrolling (frame,
frame->current_matrix, matrix, window_size,
unchanged_at_top);
}
which means do_direct_scrolling (which causes the problem) will not be
called if the terminal's scroll_region_ok flag is not set.
So given all of this, can you tell whether Emacs does TRT here? That
is:
. are all the capabilities that are supposed to be available for
these two flags are indeed available?
. do we need to check any additional capabilities, which are in fact
used in the problematic scenario, but not tested as part of
setting these two flags?
Assuming that Emacs does TRT, i.e. sets the flags correctly and uses
only the capabilities that are conditions for the flags set, then the
next important question is: why doesn't Gerd see the flickering on a
very similar system and the same terminal emulator? Is it possible
that some other local software configuration on Dmitrii's machine
causes this, directly or indirectly? E.g., Dmitrii, do you have some
display-related software/driver that has some "optimization" features
turned on? If so, can you turn them off and try again?

No, I can't reproduce this. After watching Dmitrii's video I thought it might be related to a light terminal background color (I normally use a black background), so I tried that, but no flickering.

If this happens with all terminal emulators on macOS, we should reset<br>
the line_ins_del_ok flag for macOS.=C2=A0 Look in term.c, where it is<br>
initialized by consulting various terminfo features supported by the<br>
terminal.=C2=A0 If all the features it consults indeed work on macOS, then<=
br>
simply say something like<br>
<br>
=C2=A0 #ifdef DARWIN_OS<br>
=C2=A0 =C2=A0 tty->line_ins_del_ok =3D 0;<br>
=C2=A0 #else<br>
=C2=A0 ... the current code...<br>
=C2=A0 #endif<br>
<br>
and see if the problem goes away.<br>

On my remote linux machine `line_is_del_ok` should be false where
```
tty->line_ins_del_ok
=3D (((tty->TS_ins_line || tty->TS_ins_multi_lines)
&& (tty->TS_del_line || tty->TS_del_multi_lines))
|| (tty->scroll_region_ok
&& tty->TS_fwd_scroll && tty->TS_rev_scroll));
```
because `tput al` and `tput AL` are both false and `tput sr` and `tput sf`
are false ("unknown terminfo capability").
So, disabling `line_ins_del_ok` on mac os would lead to the same
configuration I have on the linux. On the linux machine scroll never caused
any troubles.
So, would it be ok to disable `line_ins_del_ok` for Mac OS? I would send a
patch if it's OK.

If this happens with all terminal emulators on macOS, we should reset<br>
the line_ins_del_ok flag for macOS.=C2=A0 Look in term.c, where it is<br>
initialized by consulting various terminfo features supported by the<br>
terminal.=C2=A0 If all the features it consults indeed work on macOS, then<=
br>
simply say something like<br>
<br>
=C2=A0 #ifdef DARWIN_OS<br>
=C2=A0 =C2=A0 tty->line_ins_del_ok =3D 0;<br>
=C2=A0 #else<br>
=C2=A0 ... the current code...<br>
=C2=A0 #endif<br>
<br>
and see if the problem goes away.<br>

If this happens with all terminal emulators on macOS, we should reset
the line_ins_del_ok flag for macOS. Look in term.c, where it is
initialized by consulting various terminfo features supported by the
terminal. If all the features it consults indeed work on macOS, then
simply say something like
#ifdef DARWIN_OS
tty->line_ins_del_ok = 0;
#else
... the current code...
#endif
and see if the problem goes away.

All of them show the same issue. So, it is not a terminal emulator= . Additional info: When the screen flickers I alway see only 2 rectangles w/o content and they always are the same for the same scroll position. Looking into the debugger, it corresponds to the same number of insertions and insert positions. The more heavy content on the screen the more frequently the regions w/o get visible. As an option, we can add the optional flag where we can entirely disable the optimization and probably let people test it on their setups. One more possible cause is 24 bit colors in my terminal: https://github.com/syl20bnr/spacemacs/wiki/Terminal But, even when I run emacs using 256 colors: ``` echo $TERM xterm-256color ``` But, It still shows the same issue. I am open to any possible solution.

Let's ignore what I said about flushing. My assumption was that we draw the terminal content in multiple steps in different places. For example, we remove some lines, then do some logic, then we draw chars on top of it. So, if we have a lag between the operations and the terminal refreshes the screen we see only part of the content. But, as I said. Let's ignore that and if you have any guidance on how I can debug it further, it would be awesome. Flickering is consistent for some specific area. If I scroll between 2 lines, back-and-forth Emacs flickers consistently. What would be my next steps to give more debug information? -- *If you get an email from me outside of the 9-5 it is *not* because I'm always on or expect an immediate response from you; it is because of work flexibility <http://www.inc.com/john-boitnott/how-flexible-hours-can-create-a-better-work-life-balance.html> . Evening and weekend emails are a sign I allocated some regular working hours for other things (such as family, gym, friends,...).

Thank you Eli and Gerd!
Now I can run the debugger!

I use C-n/C-p (next-line).

I am trying to debug the current version w/o my patch, but probably I just
messed something up. Let's ignore this I got better results.
I am using `breakpoint set -f scroll.c -l 697`.
Currently, when I have 2 panes and I have the right pane with content on it
`do_direct_scrolling` doesn't go into the first condition in the loop. So,
It doesn't stop in the debugger. But, when I open the scratch buffer which
has only few lines and I try to scroll in the left pane on the lines where
the right buffer doesn't have any content because there are only few lines
in the buffer it stops:
```
(lldb) p *p
(matrix_elt) $3 =3D {
writecost =3D 35356
insertcost =3D 34958
deletecost =3D 35357
insertcount =3D 97
deletecount =3D 1
writecount =3D 1
}
```
... just because the cost of insertion is lower than the write cost. Then I
set the breakpoint into different line set the right window a buffer with
content:
```
(lldb) breakpoint set -f scroll.c -l 688
```
So, I see
```
(lldb) p *p
(matrix_elt) $4 =3D {
writecost =3D 54426
insertcost =3D 54996
deletecost =3D 54735
insertcount =3D 1
deletecount =3D 8
writecount =3D 148
}
```
Insert and delete cost are greater than write cost.
I see the behavior as a correct one (at least by design), but when we do
insert instead of writing the terminal flickers. Do we need to adjust some
numbers or do we have to understand the reason why we flush the content?

The following seems to work: cd src lldb emacs b main process launch --tty -- -nw -Q LLDB then opens a new terminal window with a working Emacs in it, and stops at main in the original window. One can interrupt the running Emacs by issuing process interrupt in the LLDB terminal window and so on. The process launch --tty instead of run is key here.

What exactly do you mean by "scrolling"? which keys or commands do you

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Why are you setting the breakpoint on that line?

Maybe it's a bug in LLDB. Is this specific to -nw sessions? If so, maybe LLFB has a command similar to GDB's "set new-console 1"? That's what I do to make sure the console used by GDB doesn't get messed up by the terminal setup used by Emacs to prepare the terminal for itself. Like this: $ gdb ./emacs ...

There is something about using GDB with TTY Emacs in etc/DEBUG though. Maybe that helps. LLDB doesn't work for me, neither the one from Apple, nor from LLVM 14. For some reason, SIGTTOU seems to be behave differently when running Emacs -nw under LLDB, even when I tell LLDB to not stop or report it. Or so I think, I'm not an LLDB expert. Here is what I tried cd src lldb emacs b main run -Q -nw process handle -s false -n false SIGTTOU c but then Emacs gets stuck. Maybe it's a bug in LLDB.

Do we actually need to redraw the whole line if we use relative numbers or we can just redraw the portion with line numbers?

I tried gdb and signing, but it didn't work. I also tried lldb, but it doesn't stop on a breakpoint for whatever reason. I compiled with `-O0 -g3`, then ``` lldb (lldb) file nextstep/Emacs.app/Contents/MacOS/Emacs Current executable set to '/Users/kuragin/Desktop/emacs/nextstep/Emacs.app/Contents/MacOS/Emacs' (x86_64). (lldb) breakpoint set -f scroll.c -l 270 Breakpoint 1: where =3D Emacs`do_scrolling + 485 at scroll.c:271:11, addres= s =3D 0x0000000100032da5 ``` But, it doesn't stop there... and I run Emacs like this: ``` arch --x86_64 make configure=3D"CFLAGS=3D'-O0 -g3'" -j 20 && nextstep/Emacs.app/Contents/MacOS/Emacs -nw ``` I can confirm that my patch fixes the problem for me, but I am not confident that the issue is in the estimation cost. When I have line numbers enabled, I assume, the scrolling logic would always try to insert/delete/write lines. In my case it might be: - Writing (Is that writing on top of the current lines?) is cheaper. - Screen flickers because of the specific frequency of the terminal (or the way we flush the buffer). For example, we insert empty lines and then the screen is updated, only then we add content in there and redisplay again. Potentially, some redrawing might happen inside of `ins_del_lines`? Instead of redrawing the whole screen, we redraw it in the middle of modifying it? Those are just my assumptions from reading the code. I'd appreciate any help in debugging the issue.

BTW. this was
GNU Emacs 28.1 (build 1, aarch64-apple-darwin21.3.0) of 2022-04-30
and I'm running macOS 12.5.1.
Maybe someone else having access to maxOS 11 can reproduce this?

I can reproduce the bug in the following configuration:
- Large monitor or small font in terminal.
- Having 2 vertically splitted windows.
- Enable `display-line-number-mode` on the left pane.
- Terminal flickers on scrooling on some lines.
The main point is it flickers only when the right pane has a little
content. If the file contents fits into the whole right window, the it
doesn't flicker, and it flickers only on the lines which do not have
content to display. For example,
--------------------
| | |
| | |
| |~ |
| *|* |~ |
| |~ |
| |~ |
--------------------
"~" is the part where there is no content. When I use the left window
and scroll on the lines where the right windown doesn't have content,
the screen flickers. But, as long, as I open some large file in the
right pange it works as expected w/o any flickering.
I tried to find a possible way to put some content in there, but seems
like emacs supports frigne only on GUI.
I tried different terminal emulators (iTerm2, Alacritty), in additional
to w/ and w/o tmux.
The same configuration but with ssh to linux work perfectly well. So, I
assume, it excudes terminal emulator issues.
I also tried different emacs distributions:
- https://emacsformacosx.com/
- https://github.com/jimeh/emacs-builds
- Some with come homebrew as well.
Do you have any possible ideas where I can look into it?
