Since I think yesterday I occasionally get rendering artifacts and distorted colors across the whole Firefox UI and websites. See screenshot.
This only seems to happen when webrender is enabled (gfx.webrender.all).

Firefox 73.0a1 (2019-12-03) (64-bit) (buildid 20191203094830)
macOS Catalina (10.15.1)

Can you attach your about:support as a text file?

There it is.
I reactivated webrender just now, let's see if it happens again today.

Starting today, on buildid 20191210095443, webrender enabled, see the new screenshot on what I get on all the sites now (browsing fnordig.de).

Curious if you are still seeing this?

So far not. (I also had WebRender disabled). I reenabled it and will monitor for a bit if it turns up again.

Hello! Just wanted to touch base again and see if this issue has appeared again?

It did not occur again for the past 2 months (I think I might be facing another bug now, but I'll file that when I can reproduce the issues).
This can now be closed.
