garbled screen


Since I'm using kernel, Xorg screen became garbled after some times
(see screenshot). It occurs on but seems to be less frequent (3-4
hours for ; 8-10 for
I didn't get this bug with 2.6.38

TTY stay fine and after I close and start X, everything is fine again. No need
to reboot.

I can't find anything precise which can trigger this bug, it simply occurs.
Maybe an hint, it seems to be when I try to display a minimized window.

There is nothing obvious in the logs (but I'm not using debug option), kernel
or X.

kernel  (kernel-linus- ; vanilla kernel packaged by
my distro)
xorg 1.9.3
ati 6.14.1
mesa 7.9
libdrm 2.4.24
