Thanks. It's possible there's some VT switching happening in the screen locking/unlocking. Or just mode switching. If so then that can trigger an annoying feature of the Nvidia driver where it will forget its textures:
https://www.khronos.org/registry/OpenGL/extensions/NV/NV_robustness_video_memory_purge.txt We don't yet have all the fixes we need to deal with that feature of Nvidia, and it can't be turned off either. The other bugs associated with this are bug 1876632 and bug 1855757. There's also bug 1910435 which sounds most similar to this, but the author of that bug is not responding at the moment. ** Package changed: gnome-shell (Ubuntu) => mutter (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1914164 Title: [nvidia] [radeon] Shell labels randomly disappear from the menu panel (top bar) Status in mutter package in Ubuntu: New Bug description: Description: Ubuntu 20.04.1 LTS Release: 20.04 gnome-shell: Installed: 3.36.4-1ubuntu1~20.04.2 Candidate: 3.36.4-1ubuntu1~20.04.2 Version table: *** 3.36.4-1ubuntu1~20.04.2 500 500 http://us.archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages 100 /var/lib/dpkg/status 3.36.1-5ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages Feb 1 22:09:05 tomsfastbox systemd[1]: Finished Clean php session files.
