Hi Daniel, thanks very much for having a look. What do you think then about Jonas Adahl's observations from the syscap files, that "The frame clocks together dispatches at 1000 Hz at times."? Is this expected to be triggered by firefox as well, despite the window not being in focus?
Furthermore please note, that the high cpu usage holds for almost a minute at times even after the overview animation is over! Firefox was already using the Wayland in the config I used when reporting the bug. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1999578 Title: Bursts of high CPU usage after triggering overview Status in GNOME Shell: New Status in gnome-shell package in Ubuntu: Opinion Bug description: As requested in the upstream bug report https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/6137, I hereby file the downstream issue: I am experiencing high cpu usage of gnome-shell in situations where I would not expect it, leading to my fans running more often and wasting my battery on my Dell XPS 13 9310 2-in1. The problem can be seen in action here: https://www.youtube.com/watch?v=Y9o7a7BGPE4 See also the upstream report for syscap recordings of such situations. I think there might be a correlation with firefox being opened on another workspace (but no video or any other playback happening). At least everytime I notice that my an comes on for no reason and I fire up top to see gnome shell consuming too much cpu, when I kill all my firefox windows gnome shell cpu usage goes down as well, but that could be pure coincidence. At least I can safely rule out the triple buffering downstream ubuntu mutter patch, since I recompiled mutter without the patch and it does not really change the problem much.
