Description Alexander Bergmann 2021-09-30 11:39:40 UTC

When locking the screen the application menu bar and the window list at the bottom of the screen are visible. The user has the ability to kill open windows and also start applications when the machine is locked.

Comment 1 Alexander Bergmann 2021-09-30 11:41:01 UTC

This issue was only ever present in Centos 8 Stream, in particular in gnome-shell-3.32.2-39.el8.x86_64 . No released RHEL version was ever affected by this.

Not affecting SLE / openSUSE. Closing bug as invalid.
