[arch-general] Compiz Application Switcher(Ctrl+Tab) crashes X Server

[PT M.]

i have quite a "standard" suite: [xorg18], [testing], intel-dri, Gnome,
Compiz.

when active Application Switcher of compiz several times(using Ctrl+Tab) in
sequence, X server crashes.

What I got in /var/log/Xorg.0.log, seemed to be caused by the intel-dri, is
it still lack of stability in X 1.8?
