Gnome Shell 3.8 burns my CPU

Yesterday Gnome turned 3.8, got mad, and started yelling at mah 4 double-threaded cores:
burn-480x306.jpg

A top shows a CPU charge between 400 and 700%, this only for Gnome Shell process, and, quite surprisingly, the UI slowers and suffers a little…

Switching to a good ol’ Openbox session (without Gnome) calms down my CPU, although I had to hard reboot my PC to do so (well, it doesn’t even shutdown itself : once X session is killed, and accordingly to some terminal logs, systemd successfully kills some services, then does nothing…) ; just switching from a previous gnome session to an openbox session, without rebooting, does not release the CPU, even with killing gnome-session or restarting gdm (or both).

I also tried to switch to lightdm (perhaps gdm was guilty?), then party time!! LightDM turns on and off the screen backlight (with two screens it evens does it alternatively \o/ ) and goes back to a black terminal with blinking underscore after a few seconds.

While I now enjoy a fully usable Openbox session, would you have any solution, or do I only have to wait for a more stable build?

Re: Gnome Shell 3.8 burns my CPU

rather than that description (albeit a bit funny) if you had started with the logs and journalctl, people might be able to help you more.

Re: Gnome Shell 3.8 burns my CPU

Hi there bobi; I had the same problem with Gnome 3.6 running Cinnamon whereby (sometimes) the first login will cause 4 gnome-shell processes to eat up the CPU cycles. Logging out and logging back in should fix the problem, please see if this works for you, then we know we may have the same problem.

Since upgrading to 3.8 and using the new Gnome Classic, I still had the same problem but it was happening consistently every boot.

I have since wiped all Gnome settings to start fresh, as I was switching away from Cinnamon anyways. Ever since I have not encountered the problem, but there's not been enough boots for me to confirm.

Re: Gnome Shell 3.8 burns my CPU

I see that 2 gnome-shell processes are running when I start the gnome-shell. But I always(since gnome 3.8) kill the one that's using the CPU more and the system runs fine after that.

Re: Gnome Shell 3.8 burns my CPU

Well, for what I saw I had only one gnome-shell process, very greedy indeed, but desperately alone.
Logging out and back didn’t help at all, but then I didn’t try to kill the rebellious gnome-shell process while relogging.

I’ll post journalctl as soon as I get me some time to boot directly to Gnome-Shell, stay tuned tongue
