Indeed per the upstream discussion there *might* be things that can be improved in mutter to reduce this problem. But at the same time it is somewhat expected behaviour. Only unexpected above some unknowable threshold of CPU usage that is system-dependent.
So this bug is not invalid, but also not definitely valid, currently "Opinion". -- 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.
