This sounds like another Nvidia issue related to: https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt

There is no workaround right now, other than to avoid the Nvidia driver, or to avoid user switching and suspend/resume etc :( ** Tags added: nvidia-corruption -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1901585 Title: [nvidia] Ubuntu 20.04 LTS Desktop Screen blinking/flickering black and side menu bar turn upsidedown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1901585/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
