Hi,
Could you please report this bug upstream at bugzilla.freedesktop.org
product xorg component driver/intel? You should attach xorg.conf and
Xorg.0.log. I'd be good if you could add
Option "ModeDebug" "YES"
to the Device section of your xorg.conf. Also AddARGBGLXVisuals and
AllowGLXWithComposite are probably useless.
Thanks,
Brice
