Everything freezes when I alt+tab from a fullscreen application

[Danail Dimitrov]

When I alt-tab from a fulscreen window and click on the window I want to go to with my mouse, the entire desktop freezes, instead of just opening the window I'm trying to go to. I can move my mouse around and audio is still playing, but everything is unresponsive.

Version of Ubuntu: Ubuntu 22.04.4 LTS

Update: It unfreezes if I press space twice, I don't know if this is a setting or not.
