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
