Thanks!
Couple more questions:
- Does this reproduce consistently? (I can't seem to repro locally)
- Could you see if it also happens with Webrender disabled?
To disable webrender:
open about:config in address bar
Set gfx.webrender.force-disabled to true
Restart browser - How long does the checkerboard pattern stay on the screen?

- Well, yes and no. Although I can't find any way to reproduce it step-by step from boot-up, when it happens then it's very reliable. By that I mean that it seems that certain tabs become "glitched" and stay that way. Switching to them causes the checkerboard pattern to appear.
- I will try running with webrender disabled for a few days and will report on results.
- It's only for a brief moment - it was tricky to even take a snapshot of it, because sometimes it flickers at a high rate

This was reported on Linux so blocking wr-mac doesn't seem to make much sense?

It seems that after disabling WebRender the problem disappeared.

I have observed this on rare occasions, although I have no STR at this time.

Has anyone seen this bug in the last few months?
bug 1565809 has been fixed in 73 or 74 and I haven't seen such problems since then.

Please open about:config, set gfx.webrender.all to true and restart Firefox to check if everything is fine now. Thanks!

I"m running with gfx.webrender.force-disabled set to false and I haven't seen this issue for a long time. Seems fixed to me!
