firefox_corrupt_font_with_webrender.png
User Agent: Mozilla/5.0 (X11; CrOS x86_64 13310.59.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.84 Safari/537.36
Steps to reproduce:
I'm using Firefox 80.0.1 on Debian 10 on ChromeOS 85.0.4183.84
Set gfx.webrender.all to true in about:config & restart Firefox.
Actual results:
Font rendering is corrupt. The affect is strange - the characters appear as transparent blocks with the window underneath showing through as you scroll. (In the screenshot I've got Firefox's 'about' dialog behind the main Firefox window). This also affects UI fonts.
Disabling webrender and restarting Firefox resolves the issue.
Expected results:
Fonts not corrupt.

Hi ra_hardy,
Similar bugs to this were recently fixed. Could you try Beta or Nightly version of Firefox to see if the problem is still present?
Yep, it's still present, in 81.0b9 with webrender on.
The problem occus in other apps (like VS Code) so might be a ChromeOS issue. I've raised a bug here https://bugs.chromium.org/p/chromium/issues/detail?id=1127333&q=&can=5
Closing this - it's a ChromeOS issue

"This is fixed in M86, in the meantime you can work around the issue by disabling Crostini GPU acceleration in chrome://flags"
