[Desktop-packages] [Bug 1999578] Re: Bursts of high CPU usage after triggering overview
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.

[Desktop-packages] [Bug 1999578] Re: Bursts of high CPU usage after triggering overview
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.

[Desktop-packages] [Bug 1999578] Re: Bursts of high CPU usage after triggering overview
Thanks for the bug report. In your video I can see two causes that are not really bugs: * Firefox using CPU at the same time as gnome-shell means it is Firefox causing the persistent CPU usage in gnome-shell. Make sure Firefox isn't displaying animations like web ads. Even if that doesn't look like the problem, it's still Firefox's fault if the problem is correlated with that app running. * Triggering the window spread animation causes even higher gnome-shell CPU usage. This is normal and not a bug. Although we welcome patches to make it more efficient. Suggested workaround: Make Firefox render more efficiently by adding MOZ_ENABLE_WAYLAND=1 to /etc/environment and then reboot. Also don't leave any browser tabs open that you don't need. ** Changed in: gnome-shell (Ubuntu) Status: New => 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: Unknown 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.
