Elements of a page started to disappear as I was typing text in a form (see screenshot). Not all at once, but in groups, as if the GPU cache was started to get corrupted. That's the first time I see this on the machine, currently using "77.0a1 (2020-05-03) (64-bit)" nightly.

Dzmitry, does this happen in older version of FF?

Comment 3

This is the first time I saw a corruption like this in a while. It could be a rare instance of something happening, or a new regression (on that machine I update the nightly fairly regularly, i.e. every couple of days).

Kvark, are you still seeing this? If so it would probably be good to try and use mozregression to see if we can't narrow down what has happened

Nope, haven't seen this since that time, and don't have a repro case:/
