Could you please open about:support, click on the "Copy text to clipboard" button, paste it into a text file and upload it here (Attach File)? If you can get that information after things broke, it might be even more useful. Thanks!

You said this didn't happen on old versions - can you use mozregression to identify the changes that introduced this behaviour?

For example:
mozregression --good 2018-06-01 --bad 2018-07-13 --pref gfx.webrender.all:true

Going back to look at old versions of Nightly I can't actually find a version that doesn't have the same bug. This is making me think the bug might be related to the release of macOS 10.13.6 as that was around the time when I started noticing the bug, although I haven't had issues in any other applications.

So ran into the bug in a new situation, I had only 1 firefox window open which normally works fine with webrender and then I opened a RAW photo in macOS's Preview app and the Firefox window got corrupted. So other applications can trigger the corruption in Firefox but are fine themselves.

FWIW I did a check for macOS updates on my older MacBook Air running 10.13.5, and there were no updates available. Assuming you got the 10.13.6 update via the usual mechanism, Apple might have pulled the update due to this or other issues. At any rate we'll have to wait and see if the issue persists when they do release 10.13.6 (again).

Attached is a screenshot from an Apple service document somebody shared online on a thread I found with other people also experiencing graphics issues since updating that details some graphical issues in recent versions of macOS.

Do you still see this issue? There has been lots of changes and improvements to WebRender since the original filing of this bug.
Have not been able to repro this on 10.13.6
