It's possible the Chromium/Electron thing is this bug[1], which affects new proprietary nvidia drivers on recent Chromium versions. I also experienced that bug, though I don't think it affected Firefox for me. It resolved itself for me recently in all apps except Slack. I have no idea why. I'm fairly sure I didn't update anything. While it was still reproducing, I tested a purported fix in the upcoming Chromium 87 (or 88?) and it was resolved. So just wait a bit or try Canary. More specific info in the bug thread of course. [1] https://bugs.chromium.org/p/chromium/issues/detail?id=1113040 https://bugs.chromium.org/p/chromium/issues/detail?id=111304...
