It looks like the overview that normally launches when you click at the super key, but without search bar and without the possibility to leave the view again (via ESC Key, etc.). Only logging out and in again solves the problem.

I can choose from the running applications or write a command into the text window. After I chose an application or press ESC all this disappear and I can do my thing. Since trying 21.04 sometimes this 1. does not appear properly - there is no visible text window 2. does not disappear - despite what I click on or what keys do I press this never disappear so I can not use my running applications or start anything new even from the menu. I have to log out and in to break this. Disabling my gnome-shell extensions or using xorg instead of wayland does not helps. Since upgrading this morning this happens every time I press Super, not just occasionally, thus making my desktop unusable.
