Comment # 10 on bug 1185267 from Gregory Baudet

I think I have similar issue. When I try to use Firefox ESR 91 or Firefox 92,
the GUI is not responding and not refreshing properly.
Moving the window on the display, minimizing seems to force the Firefox GUI to
refresh.
There is no CPU load.
Safe mode doesn't help.
New profile doesn't help.

I use opensuse Leap 15.3 with xfce.
I'm not using exotic packages or repository.
I have intel hd graphics CPU, no additional GPU.
I haven't tried yet the workarounds proposed here.
Firefox 78 works fine on the same setup.
