Description

I don't have precise STR, but I noticed this yesterday, restarted my browser, and then it reoccurred after browsing for a while.

Here's a short video:

It looks like either we run out of some sort of resource or something gets corrupted, and then we intermittently draw black rectangles and red-tinted images.

I recorded this gif yesterday of what seems to be the same issue, but where elements are intermittently drawn with a red tinge:

This happens frequently enough to me that I had to disable webrender on Windows to preserve my sanity. It seems to show up on Twitter most often, although maybe that's just because I use Twitter a lot in this browser.

Try setting gfx.webrender.force-angle to false. If it helps, this bug would be a duplicate of bug 1421696.

I flipped this pref on Friday but I didn't use this machine much over the weekend. I haven't seen it reoccur yet though so I suspect you're right.
