Subject: 27.0.50; Emacs doesn't render text/modeline Mac OSX 10.14 Mojave
Date: Tue, 19 Jun 2018 16:09:03 -0700

Emacs from the master branch compiles on Mac OS 10.14 (Developer Beta 1
and 2) just fine, but when I run the resulting Emacs.app, none of the
text or even the mode-line appears in the frame.

- If I "select" the text in the scratch buffer, I see nothing, but I can
  then paste it into another application just fine.

- If I type something in the scratch buffer, I can't see it. I can
  select it (but not see the region), copy it, and paste it into another
  application and see the text I've typed.

- The mode-line isn't rendered, either.

- Running Emacs.app/Contents/MacOS/Emacs -nw in a terminal window works
  fine.
  
The application seems to be working in all particulars except the text
is invisible (not the same color as the background, just not there).

I can see how this might be less than ideal.

Can you please recompile and send the output? I expect there are a few
deprecation notices, perhaps one of them will give us a hint as to
what’s going on here.

Here’s the bit involved with the NS stuff. Yes, plenty of deprecations, though that’s been going on for quite a few iterations.

For what it’s worth, the scratch/ns-drawing branch has fixed this for me.

Thanks for the confirmation.

I think I’ll have to port it to Emacs 26. It’s quite a large change,
but if Emacs 26 in its current form simply doesn’t work at all with
the next release of macOS I don’t see that we have much choice.

Can you please try the attached patch against emacs-26?

I’ll try the patch and get back to you today. However, I don’t actually know how to apply patches (it’s been years) so this may take some time. ;)

[Message part 1 (text/plain, inline)]

OK.

The patch worked just fine.

Details:

Using Xcode-beta5:

git checkout emacs-26
gmake clean
cd src 
patch < ../path/to/your/path
cd ..
gmake install
cp -r nextstep/Emacs.app /Applications/

Hopefully that’s a reasonable path to rebuilding and running.

I then launched and can see all the rendered text just fine.

Also, switching to “Dark Mode” changes the window-title bar to the correct color.

Subjective, but scrolling seems faster, somehow.

Another wrinkle (emacs-26 with patch applied):

When I change my font, all the text disappears except for the current line.

The text comes back if:

- I move the cursor over the affected areas.
- I wait a bit (from the cursor line down renders).
- Switch away to a non-Emacs window.

Seems like as soon as there’s a reason to paint the screen, it comes back.

Functions I use:

(defun kfi/set-font (name weight)

I take it the frame changes size when you change font?

If you evaluate this does the frame redraw right?

  (set-frame-width nil 103)

Yes, that works fine. You might want to apply the patch using

    git am path/to/patch

That inserts the patch as a commit in git, but it makes no real
difference.

I thought I was going to have a make a change to get that working.
Does the scrollbar change with it?

Both the scroll bars and tool bar change color with the overall appearance settings. I’m guessing that compilation links against the correct libraries which do the Right Thing.

An instance compiled elsewhere (on High Sierra) ignores the Dark/Light mode changes.

The frame’s size does not change (if you mean the window gets narrower for a narrower font, say).

The set-frame-width expression doesn’t make any difference when I change from Monoco to Menlo and back.

Another interesting thing:

* The problem does NOT occur when changing the size of the font.

* If I change the font (to Monaco), the screen blanks, but immediately running a command to change the font size “fixes” it.

Seems that the font-change isn’t triggering a “repaint the whole thing”, rather, just repaint the line containing the pointer.


Functions involved in font-size change (really just set-face-attribute):

(defun kfi/set-font-size (size)
  "Set the font SIZE."
  (interactive "nNew size: ")
  (set-face-attribute 'default nil :height size))

(defun kfi/font-size-up ()
  "Shift font size up by 10 units."
  (interactive)
  (kfi/set-font-size (+ (face-attribute 'default :height) 10)))

(defun kfi/font-size-down ()
  "Shift font size down by 10 units."
  (interactive)
  (kfi/set-font-size (- (face-attribute 'default :height) 10)))

Yes, that sounds right. Chances are the line with the cursor on it
redraws because the cursor is drawn as a separate action.

Probably the font change needs to mark the frame as garbaged so it’s
redrawn completely, but that’s not happening. Unfortunately I don’t
know where that should be done. I can’t see anywhere obvious in the NS
code. I’ll keep looking.

[Message part 1 (text/plain, inline)]

Hi all,

I usually use Emacs 27 (AKA `master`). I upgraded to the latest Mojave 
beta (1 week until GM I believe, I was eager!)

Thanks Alan for providing the patch, I took the patch (which you said 
was based on emacs-26) and "updated"
(used the `wiggle` command for the hunks that wouldn't apply, I've never 
really meddled with Objective-C before and
I've never really updated a patch before when there's rejected hunks, so 
please excuse any ignorance you pick up on. :-)

The patch builds and launches Emacs successfully! (Thanks again Alan)

However, just thought I'd mention that after some time (5-10 minutes of 
idling, and just now it crashed during launch) I get the following:

Note that I *believe* I've compiled Emacs with debugging symbols and no 
optimisation, feel free to correct me if not.

Hopefully the below output is helpful to someone. This might even be a 
bug in Mojave and one of the core libraries, but I haven't had
this with other applications:

I can reproduce the issue within a maximum of 10 minutes, whether typing 
or not.

It's likely worthy to note that this happened also with the emacs-26 
branch, commit d4fa83baf5462cfcf61ebbb8c0a0ec584d11c39a,
under the same circumstances, and with the attached patch applied.

Feel free to shout at me to submit this as a new bug, I couldn't find 
which email makes a new one. :-(

The below happens on commit 75d9a55fae1c484aa6d213064931bfe3b65cf5dd on 
the master branch.

What's the status here?  I can see that some code has been added in
reference to this bug in commit 7946445962372c42, but I'm not sure if
that fixed all outstanding issues.

I don't have macOS 10.14 so I can't test any of this myself.

Best regards,

IIRC I’ve left this bug open as a centre for any further reports about
issues with macOS drawing. It’s not been resolved, and I have an
alternative approach, but I don’t seem to have the ability to complete
it (I’m absolutely fed up with Apple’s developer unfriendly approach
towards documenting their APIs).
