On XUbuntu 20.10: I upgraded Firefox from version 87 to 88 today. Now, its window doesn't redraw/rerender its content. The windows redraw/rerender once only when I resize them.

What I tried

  • Safemode solves the problem
  • Disabling all addons does not help



Does anyone have a solution for this?

  • No problem with FF 88 on ubuntu 20.04.2 here. is it worth checking with bugzilla.mozilla.org as a bug report?

  • There are nowadays graphical issues with the current 5.8.0-50 kernel. Perhaps try booting to 5.8.0-48 to see whether the problem then also occurs. Otherwise, probably disabling hardware acceleration may stop the problem (at the expense of graphical performance).

  • No bug report found; kernel 5.8.0-49 (before the latest sys update) has same problem. turning off HW accel did the trick

As a workaround: disabling hardware acceleration worked:

  • open browser in safe mode (firefox --safe-mode)
  • type about:preferences in address bar
  • search for hardware
  • uncheck use recommended performance settings
  • uncheck use hardware acceleration
