Good day!

I've described this bug here:
https://github.com/hlissner/doom-emacs/issues/5469

During investigation I've discovered the exact commit which brokes
toolbar on this scenario.

Let me share git bisect log:

I can't for the life of my see why that commit should break it, but
can you please try the attached patch and see if it fixes the problem?
I can't replicate it here.

From: Alan Third <alan@idiocy.org>

Subject: [PATCH] Fix incorrectly appearing toolbar on NS (bug#50534)

* src/nsterm.h (FRAME_TOOLBAR_P): Work out whether the frame should
have a toolbar or not.
* src/nsterm.m (ns_update_begin):
([EmacsView windowDidEnterFullScreen]):
([EmacsView windowDidExitFullScreen]): Use new FRAME_TOOLBAR_P instead
of the apparently unreliable FRAME_EXTERNAL_TOOL_BAR.

have a toolbar or not.

([EmacsView windowDidEnterFullScreen]):
([EmacsView windowDidExitFullScreen]): Use new FRAME_TOOLBAR_P instead
of the apparently unreliable FRAME_EXTERNAL_TOOL_BAR.
* src/nsmenu.m (update_frame_tool_bar): Use new FRAME_TOOLBAR_P.

Turns out it doesn't, it just prevents the toolbar from appearing at
all.

What's the value of (frame-parameter nil 'tool-bar-lines) once the
frame has loaded with the toolbar visible?

And can you perhaps try commenting out the call to
update_frame_tool_bar on line 8328 of nsterm.m?

Maybe it can be for some use.

I've attached the minimal patch which fixed issue for me.

This patch reverted some of your changes.

Because when I move to full screen => toolbar is dissapear, I feel that the root cause is replacing layoutSublayersOfLayer to layout.

Anyway, I don't know quartz and I can't minimize it future.

It has to be a timing issue. None of the code you're changing touches
the toolbar or its visibility, directly or indirectly, so any change
there can only be altering when various pieces of code are called.

Changing to and from fullscreen explicitly resets the toolbar's
visibility.

I think what we probably want to do is default the toolbar to
non-visible when it's created (at the moment it's using the default,
which I suspect is visible), and then rely on the fact that
update_frame_tool_bar is always called when it should be visible to
turn it back on.

Patch attached.

The *only* place that should modify FRAME_EXTERNAL_TOOL_BAR is
ns_set_tool_bar_lines, which should be called *every time* the number
of lines is changed.

It would be nice to know what the value of FRAME_EXTERNAL_TOOL_BAR and
tool-bar-lines are when the toolbar is wrongly visible, because I
can't find a single location in the code that sets the visibility
without first checking FRAME_EXTERNAL_TOOL_BAR, and it should *always*
be set by ns_set_tool_bar_lines.

*sigh* I've no idea.

Attached is the nuclear option. If this doesn't work then
FRAME_EXTERNAL_TOOL_BAR is wrong.

Hey,

I haven't yet tested your last patch.

Right now I'm on 1e83d04214f27a79a4d4841772da946e24cbf21d as local root and it starts to have wired visual things like that:


Before your last patches everything was fine.

regarding my last screenshot.

I found a way to reproduce it. When I create a new frame via `New Frame` from menu inside Dock => it brokes lines inside emacs.



After I've working with emacs for a while. A while mean 30-40 minutes or more with active switching between frames and virtual screen on macOS.

This last patch breaks toolbar display on my Mac.

I think probably the best option is to change the toolbar handling so
it actually just removes the toolbar when we don't want to display it.
I really don't understand why the NS port goes to great lengths to
hide it. If we remove it then it can never be displayed when it
shouldn't be, and if it's attached to the window then it should always
be displayed, so we don't have to concern ourselves with making sure
the settings match after the window is resized or whatever.

Can you please try the attached patch and check that the toolbar is
behaving as expected.

It seems to work correctly here everywhere (except in GNUstep we
sometimes get an extra tall toolbar, but I doubt anyone cares too much
about that), but I think it may have removed the animation when the
toolbar is attached to the frame.

If anyone is really upset about the animation (and I'm not even sure
it IS gone) then we probably just need to create the toolbar as
invisible and attach it then mark it visible, but only do that on
Cocoa as it breaks the toolbar on frame creation in GNUstep.

Looks fine here, thank you! Didn't see any animation but can't say I miss that.

I'm reasonably sure this should sort Kirill's problem too, so I've
pushed it to master.

Alan,

I just tried ccb35fb8fb9de5f069fd0103f24e3048d716febc as local root and would like to confirm that fix still hold.

BTW, I also opened bug#50641 and I feel that it can be related.

Why? Because crashes started at the same time, when this issue was discovered by me.

FYI:

I observe the bug on my Mac as well. When I execute M-x and 
tool-bar-mode, it says "Tool-bar mode enabled" or "Tool-bar mode 
disabled", but no matter what the message says, the tool bar does 
its own thing. Sometimes, Emacs says "Tool-bar mode enabled", and 
the tool bar hides. Other times, the opposite happens, or the 
command does nothing at all, despite Emacs saying that it enabled 
or disabled the tool bar. Chaos!

I observe the above on Emacs 28 from master, commit 
0934363c96ff774ce242b51529688bbfbb48ba02, which includes 
1e83d04214 * Fix incorrectly appearing toolbar on NS (bug#50534).
