Steps to reproduce: 1- Goto https://lichess.org 2- Move the pointer around, hovering the various UI widgets in the page, also click on some menu (even start a game if you fancy) Expected outcome: Good rendering Actual outcome: Tons of rendering artifacts, a lot of stuff drawn on places where they should not be Looked like the typical issue with AC, so I tried WEBKIT_DISABLE_COMPOSITING_MODE=1 and then everything works fine.

If it's a regression from 2.20.3, then please mark this as a duplicate of bug #188377. Carlos Garcia will do a fixup release next week.

I don't think it's a regression from 2.20.3 as I've seen it for a while now, like 3-4 months at least. I'll wait for next release and close it if it's really caused by the same change that fixed the other bug.

No, it's a separate issue, then.

It turned out that 2.20.5 fixed this too, so the root cause was the same. Working fine now. *** This bug has been marked as a duplicate of bug 188377 ***
