The top-left corner in Gnome contains a dash and dot that seem related to the number of workspaces instead of the usual “Activities”. The name of the foreground application never appears in the top bar. As a consequence, it is not possible to access the active application’s main menu. Clicking the dash-dot at the top-left corner opens the Activities overview as before.
This affects newly created user accounts with no gnome extensions, customizations or changes.
Is this affecting anyone else?
