bug#32932: 27.0.50; render bugs on macOS Mojave

[Boris Buliga]

I have the same issue.

Usually, it happens during resizing. But I've seen it several times without resizing.

The same, let me know if you need any help to track it down.

I have another way to reproduce it—by resizing the frame. Occasionally
it’ll fail to paint the entire frame. It appears that I can only
reproduce it while the point is on something that triggers an eldoc
tip in the minibuffer.

I wasn’t able to record a gif of it (any screenshot or gif I record
acts as if it painted successfully) but the video I attached shows the
behavior. I can’t say for certain that this is the same thing I see in
normal usage when I’m not resizing things, but it certainly looks to
be the same type of artifact. Sometimes it’s a previous painting
that’s left around and sometimes it’s a blank. I’m sure it’s a blank
in this case because it blanks while resizing.

Hopefully that helps track it down. Let me know if there’s anything
you’d like me to try.

Thanks,

Aaron
