Hi, I noticed I have installed an ancient kernel-5.11.17-300.fc34.x86_64, thus I booted it, but it did not help. I updated the https://people.gnome.org/~mcrha/glitches.mp4 , it shows how Firefox draws its menu when moving mouse above the items. I realized I've disabled compositing manager in MATE (gsettings get org.mate.Marco.general compositing-manager). When I enable it the things get much better, the Firefox stops misbehaving in the menu. I do not know why it had been disabled, the machine is updated from Fedora to Fedora, for years. The compositing-manager has some side effects I'm not used to (the way things are drawn in the desktop environment), but I guess I can live with it. One last question: is the hardware acceleration meant to work also without the compositing-manager? I do not know whether GNOME Shell has a way to disable it and whether it would work similarly odd there as well, though maybe it would worth a try. Anyway, consider this fixed. Thanks a lot for your help.
