As this is on the r600 driver it's likely a duplicate of bug 1679681 which unintentionally got fixed in bug 1694909. Vitaly, could you test if things are fixed on nightly / FF 88 for you?

Thanks! Marking as duplicate of bug 1679681 then. You can work around the issue be setting gfx.webrender.force-disabled:true in about:config.

Andrew, looks like this bug affects Mesa r600 users on 86-87. Can we block WR for that driver until 88? Thanks!
