Getting really high CPU usage by gnome-shell after 3.24 upgrade

We're talking cpu usage in the 80% of a single core.  With extensions disabled.  Anyone got any clues as to why?

I might try some of the other gtk-based desktops to see if it's gnome-shell specifically but other than that I am a little out of ideas.

Update: Only Budgie also seems to have issues, which is also the only other one linked to the normal Gnome components.  In which case it might be a mutter issue I suppose, but even with that knowledge I am still stumped as to why such high CPU usage

gnome-shell  Budgie mutter

=> When talking about "high CPU usage by gnome-shell", do you refer to the session or the process?
If "the session" it might pay off to check which process it actually is...

Are you by any chance using NVIDIA? if so, try rebuilding mutter with this patch reverted.

The gnome-shell process, and also the budgie window manager process.

Will give that a try

Re: Getting really high CPU usage by gnome-shell after 3.24 upgrade

Just a quick reply: Got a similar issue, updated the system today (lots of new gnome stuff), and now gnome shell constantly uses 8-10% cpu on 4 cores / 8 threads (Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz).

I do not have time to dive into the issue right now, but maybe for a quick confirm my pacman.log | grep gnome:

Re: Getting really high CPU usage by gnome-shell after 3.24 upgrade

I can confirm that reverting this patch (https://git.gnome.org/browse/mutter/com … caedef06b6) as suggested by @hussam solves this abnormal behavior.

I've noticed something though. Although before the patch, the window movements has been really fast and smooth but as a result it resulted into high cpu usage. With this patch I am getting the old behavior back where window movements were still fast and smooth but they were slower than the new release (3.24.1). But I am sticking with this patch, because the CPU with this reverted patch is back to normal.

Re: Getting really high CPU usage by gnome-shell after 3.24 upgrade

It seems that it has been fixed in either mutter or directly the nvidia drivers. I am not longer having cpu issues with the animations and whatsoever and the cpu usage is still kinda high (20% when doing all kinds of animations) but it's the old behavior. Also the animations are kinda faster than before eg. moving a window around feels super smooth.
