Hi all,
Everyday since the installation of my system, Gnome 3 loses its mind and uses 100% CPU usage (vs ~4% usually). It lasts forever and makes the system slow.
I'm tired of typing Alt-F2 and "r" to restart it so I try to debug it. Unfortunately, Gnome 3 does not log any errors while "bugging".
I don't know how to get info on this unexpected usage. I've just made a strace here.
Can someone point me out how to get more info on this ?
Thanks in advance.

I believe any errors from gnome-shell should appear in your journal.
You should also be able to do some debugging with gnome-shell's looking glass. Enter "lg" to the Alt+F2 dialog to use it.
If it doesn't work you need to enable org.gnome.shell.development-tools with dconf-editor or gsettings.
I don't know how to read the strace, but the recurring "Resource temporarily unavailable" message looks important.
did you try disabling all your extensions already?

In fact I never tried to disable all my extensions (idiot) and ... the result is there : it seems I've managed to isolate the problem, it was the "place-windows-in-center" extension which causes problem. So I disabled it.
This extension wasn't supported on gnome 3.18 and a simple gconf tweak made the same job (even cleaner ! Look at /org/gnome/mutter/, and check 'center-new-windows').
Anyway, will report in one week if resolved. Thanks again for pointing out this. ;-)
