You have been subscribed to a public bug: I recently updated from Ubuntu 20.04 to 22.04 and am experiencing significantly more lag. The most noticeable one is when entering and leaving the workspace overview. In 20.04 this was very fast (~0.5 seconds?) and now it is taking ~2.8s after pressing Windows key before I can see the workspace overview and click to a different window or search for an application. The same in reverse; ~2.8s after pressing Esc or Windows key before I am returned control inside an application.
I currently have some extensions installed but removed them all and was experiencing the same thing. This still occurs if I have no windows opened.
