Hi there, with the Debian update from 11 to 12 came the switch from Gnome 3 to 4. This causes a huge performance problem in the “Activities” action I need to perform literally all the time, to switch between application windows. In the old system, this was very snappy, in the new system already four or five windows mean the computer practically freezes for a few hundred milliseconds including a frozen mouse pointer. It feels very awful. I would estimate the old version was at least four to eight times faster.

I’m on an HP laptop with Intel onboard graphics. I didn’t change anything with the Debian 11 to 12 update. Any help fixing this issue is appreciated. Ideally the overview would come immediately and the windows would be refreshed asynchronously, because now, if I have like ten PDFs open, it’s completely unusable. I would prefer not to switch window manager, just because Gnome 4 assumes everyone got a ten times faster machine than five years ago. I am sure this a bug somewhere.
