Public bug reported: 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. ** Affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Tags: kinetic ** Attachment added: "apport.gnome-shell.4sllnc5r.apport" https://bugs.launchpad.net/bugs/1999578/+attachment/5635523/+files/apport.gnome-shell.4sllnc5r.apport -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1999578 Title: Bursts of high CPU usage after triggering overview To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1999578/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
