--- Comment #91 from Programmist11180 programmer11180@programist.ru --- Symptoms same as on screenshots in attachments.

I found out that graphics corruption appears with this /etc/X11/xorg.conf

Section "Device" Identifier "Radeon" Driver "radeon" Option "EXAPixmaps" "off" EndSection

When "EXAPixmaps" is "on", no graphic corruption. It is fair for ALL kernels that I tested (3.2 , 3.12 , 3.13rc6). Appears only in applications that used opengl (glxgears for example).
