Public bug reported: I noticed this problem immediately after updating GNOME Shell to 3.28.3 this afternoon.
If I log in the super key works as normal as does "Show Applications". If I then start an application and then use the super key I cannot again use any open application. I have to close applications from the launcher. Logging out and back in again is necessary to restore proper functionality. At first I thought this would only affect my main user but I also have two other users set up. Their profiles have not been customised. I see the same behaviour with both users. Any display of Activities or Show Applications prohibits any further use of opened programs. I've disabled all extensions but the problem remains.
