Description of problem: I don't know exactly what the problem is but this is what happens: Sometimes when I have some application open like firefox and try to open steam or some other game in full-screen, the game rendering is too slow. The most strange part of this behaviour: If I press "super" key I see the same game running smoothly, and now if I change to some other window and then press "super" and go back to the full-screen game it moves pretty well. It only happens in wayland gnome session. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. check the description 2. 3. Actual results: Expected results: Additional info:
Created attachment 1768865 [details] desktop recording that shows the behaviour In the video you will see the behaviour, on last switch between gnome-terminal and the game itself it doesn't shows anything but after that last switch it is working fine.

This sounds like https://gitlab.gnome.org/GNOME/mutter/-/issues/1636 .
That was brought up on the report I mentioned earlier
(In reply to Michel Dänzer from comment #3) > This sounds like https://gitlab.gnome.org/GNOME/mutter/-/issues/1636 . Note that this is separate from https://gitlab.gnome.org/GNOME/mutter/-/issues/1699 . There's an upstream fix which fixed #1699 for me, but not #1636.
BTW, the attached video didn't properly capture the problem due to https://gitlab.gnome.org/GNOME/mutter/-/issues/1707 .
