It happened to me 3 or 4 times. Suddenly, when I switch to Firefox, the window is black. All firefox windows of the same profile (another profile that was running stays unaffected), in all the workspaces.
Sometimes hardware acceleration can cause issues. In about:config check media.hardware-video-decoding.enabled (default true) media.hardware-video-decoding.force-enabled (default false) You can test disabling the first and see if that prevents the problem to begin with. (I had similar issues in the past, but past year or so I haven't see the issue again) Also, if you have another app that demands high-res graphics -- that can cause problems in FF as well. (it shouldn't, but I have had that happen) I don't know if X or Wayland or the graphics driver is the cause of it. Or it may be a cock-up in Gtk that is the cause. -- David C. Rankin, J.D.,P.E.
