Please tell your GTK version (and preferably all the other
information collected by "M-x report-emacs-bug RET").

Thanks.

P.S. Do I understand correctly that these messages are emitted only
for that combination of colors?

No, setting background-color to any value will cause the errors

Do the problems go away if you disable the scroll bars?

All of them.

"M-x scroll-bar-mode RET" should toggle display of vertical scroll
bars.  "M-x horizontal-scroll-bar-mode RET" should do the same with
horizontal scroll bars.

They only happen one at startup, if if put in my .emacs:
   (scroll-bar-mode 0)
They are gone.

Great, then my guess was correct.  These warnings come from
xg_update_scrollbar_pos and from xg_finish_scroll_bar_creation.  Can
some GTK expert try to find out why the scroll-bar widget seems to be
reported as invalid)?  Robert, are you there?

Thanks.

I can't reproduce this under Gnome or KDE, with the same GTK version.
Which window manager/desktop environment is being used here?

I don't have that GTK version installed to test here.  But note this
question of the OP:

> The left side scroll bar?

By default, GTK builds show scroll bars on the right so either he has
customized them already (which makes me wonder why he asked how to
turn off scroll bars) or other strange things are going on.

Ah, the configure command has '--without-toolkit-scroll-bars', so the
error is even more mystifying.

I can't reproduce even with '--without-toolkit-scroll-bars'.

This is all under X11 though, perhaps the OP is using Wayland?

I have not, maybe Gentoo has ?

X11

I now did some more test and found that (require 'ecb) is also needed.

Here is my .emacs;

;(scroll-bar-mode 0)
(setq inhibit-splash-screen t)
(global-set-key "\C-cg" 'goto-line)
(require 'ecb)
;; Color settings.
(setq default-frame-alist '((background-color . "#333333") (foreground-color . "White") (cursor-color . "White")))
(setq initial-frame-alist default-frame-alist)

(defun my-commit-mode()
(ispell-change-dictionary "en")
;; Flyspell commit msgs
(flyspell-mode)
;; Do not create svn-commit.tmp~ backup file
(set (make-local-variable 'backup-inhibited) t))

(setq auto-mode-alist (cons '("/svn-commit\\.tmp\\'" . my-commit-mode)
auto-mode-alist))

(setq auto-mode-alist (cons '("COMMIT_EDITMSG" . my-commit-mode)
auto-mode-alist))

With that I can reproduce it. '--without-toolkit-scroll-bars' is
required, which narrows down the potential source a lot.

So I donʼt think we should be calling GTK functions on scrollbars that
are not GTK widgets (Iʼm stunned we've never seen this before). This
fixes it for me. Martin?

Setting the background color on a GTK build without GTK scroll bars
seems pretty rare to me.  In addition, one usually has to look at the
console to see the warnings.

Do we want to skip xg_set_widget_bg too?

I can't see a code path where that would get called in the non-toolkit
case, but the code is a twisty maze of similar functions.

Don't we want to fix toolkit (GTK) builds with non-toolkit scroll bars
here?  Or am I missing something?

We do, but I only see xg_set_widget_bg getting called on scrollbar
widgets when USE_TOOLKIT_SCROLL_BARS is set, in which case they're GTK
widgets, so thatʼs the right thing to do.

I apologize for my stubbornness.

xg_set_background_color (struct frame *f, unsigned long bg)

has

      xg_set_widget_bg (f, FRAME_GTK_WIDGET (f), FRAME_BACKGROUND_PIXEL (f));

which IIUC does not work on scrollbar widgets.

There is only one call to xg_set_background_color, from xfns.c, which looks
like this with my patch applied:

#ifdef USE_TOOLKIT_SCROLL_BARS
# ifdef USE_GTK
      xg_set_background_color (f, bg);
# endif
#else

So it will only ever happen when the scrollbars are GTK widgets.

But this effectively throws out the baby - painting the background of
the frame widget proper via

      xg_set_widget_bg (f, FRAME_GTK_WIDGET (f), FRAME_BACKGROUND_PIXEL (f));

with the bathwater - painting the background of non-existent scroll
bar widgets via

          xg_set_widget_bg (f, webox, FRAME_BACKGROUND_PIXEL (f));

for GTK builds with native Emacs scroll bars.  Maybe on X the

      XSetWindowBackground (dpy, FRAME_X_WINDOW (f), bg);

in x_set_background_color would take care of that.  But are we sure?

Iʼm being particularly dense today: youʼre right. How about moving the
check for USE_TOOLKIT_SCROLL_BARS down into xg_set_background_color
like so (which I think was your original suggestion):

Sounds reasonable.

I think whatever the changes you eventually come up with, they should
be pushed to the emacs-26 branch.  Do you (both) agree?

Sure. Eli, is the following OK for you? Itʼs a pretty rare setup, so
master would probably be fine as well.

I just got to ask you guys something that bugs me, why do I have have both:
;; Color settings.
(setq default-frame-alist '((background-color . "#333333") (foreground-color . "White") (cursor-color . "White")))
(setq initial-frame-alist default-frame-alist)

I think one of the should inherit the other.

Throw away the second form.  It's redundant.

But I cannot, the color settings will not work, just tried it to confirm.

Usually from the terminal, no args other than file names.
Unless I have the new colors in both variables, it wont display the right colors.
Just try with my values. Either the first or the second Frame gets different colors.

Any non-default command-line options?  Do you have something in your
~/.Xdefaults or in site-init file?  Anything else in your ~/.emacs or
other init files besides those two lines?

I just tried that, and I cannot reproduce what you describe.  The
first setting alone, for the default-frame-alist, is enough to set the
colors for the initial frame and all other frames I create.  As I
would expect, and as Martin said.  initial-frame-alist is only needed
if you want the initial frame to look different from all the rest.

So some other factor is at work here, most probably in your other
customizations.

They work here in a GTK build of master without toolkit scroll bars.

That's a lot to consume.  Let's start from the other end: if you have
only this line in your .emacs:

  (setq initial-frame-alist '((background-color . "#333333") (foreground-color . "White") (cursor-color . "White")))

does it then work as expected?

And if you invoke Emacs with "emacs --no-x-resources"?

That works ! :)
I only need default-frame-alist settings then.

As expected.  X resources override .emacs, at least for the colors.

Yes, looks like that.

Not quite to me in this case. I would expect initial frame inherit default frame 
in this case too.
