Windows disappearing unless in Activities view
Affected version
- Ubuntu Focal Fossa
- gnome-shell 3.34.3-1ubuntu1
- XOrg
Bug summary
It's happened to me twice after a recent update that I couldn't reach a window, even though it was visible in the Activities view and listed on the launcher.
The windows seemed to take focus, but couldn't be seen. Alt+Tab switching didn't help either.
