I still need to try this with emacs -Q, but I have seen this for some
time now (possibly since Alan's recent batch of changes to macOS
rendering)

If I am screen sharing on zoom, I will often issue a command that I
expect to repaint the frame and it will not. If I issue another then it
repaints immediately with both commands having been realized. This
*only* happens when screen sharing with Zoom. I will try other screen
sharing software to see if it is a Zoom specific thing. I am typically
sharing just the Emacs window (and maybe an iTerm and a browser), but
never full screen sharing.

Alan, is there anything that you could think of that could cause
something like this to happen? Is there logging I could add to help get
to the bottom of it?

Thanks,

Aaron

I have the same problem (every day) but with the open-source Jitsi screen-sharing program.

Do you have inhibit-double-buffering set to t? I'm trying setting that
to nil, to see if that helps.

FYI: I have just tried both t and nil, and it does not make any difference.

Probably the first thing you could do is check that [EmacsLayer
display] is being called at the right time.

But I can't really think of any particular reason for this to happen.

I'm pretty sure that variable does nothing on NS.

How do I enable and observe NSTRACE?

Uncomment the line at nsterm.h:65, and probably the one at line 78
too, which refers to NSTRACE_GROUP_FOCUS.

It logs to the terminal or to the system logs.

Addendum: Sharing Emacs *window* with Jitsi works great.  Sharing the entire *screen* does not.  There, Emacs slowly "falls apart", redrawing erratically (for the remote viewer).

Hmm, I see logging but typically every keypress is met with:

nsterm.m  : 6100: [11784]  [EmacsView keyDown:]
nsterm.m  : 6393: [11785]  | [EmacsView hasMarkedText]
nsterm.m  : 6284: [11786]  | [EmacsView insertText:]


I see some [EmacsLayer display] but very few. I'm not sure how to
trigger them. Is that what is expected?

I have a fairly hard time reproducing this whole thing so even though
I'm screensharing right now and running a test build...

Rudolf, if you can reproduce it consistently could you try the
building with that logging enabled?

I found that the bug I experience applies to all software, not just Emacs.  Thus, disregard all my words above.  I apologize for chiming in without doing any basic investigation.

(For the sake of completeness, I also found that the screen "falls apart" only when I share a screen different than the one Firefox/Jitsi exist on.)
