[arch-general] Gnome Shell freezes

Dear arch users and developers,

I have posted this issue also in the archlinux forum [1]. I didn't get
much feedback there. So I'm hoping some people here might have an idea
of how to resolve the problem.

gnome shell freezes from time to time (actually daily).

"Freezing" means, the screen becomes unresponsive but everything seems
to continue working (sound and videos continue playing; even the mouse
pointer can still be moved). Most of the time I'm able to switch to a
virtual console although sometimes it takes 10-20 seconds after
CTRL+ALT+F1 to show up. Then, however, everything is running smoothly.
It's not possible to restart X since it will freeze again at the gdm
login screen, or even without using gdm when loading the desktop.

What triggers the problem:
Usually it happens while scrolling on websites or pdfs. I feel like it
happens more often if there are large images.

ATI X1400

I think it's an issue with the open source radeon drivers. However, this
problem doesn't occur using other desktop environments. I tried to look
into some log files but I couldn't find noticeable error messages.

Looking forward to your suggestions,
