Created attachment 20282 [details] corrupted screen with opengl app Hi, I have hp pavilion dv6000 laptop with 965 GM graphics running OpenSUSE 11 64 bit. Xorg version 7.4 from OpenSUSE XOrg/openSUSE_11.0/ repository. While running opengl applications (blender or vlc with output type set to OpenGL) the screen is highly corrupted - see attached screenshot. For reference, the original issue were http://bugs.freedesktop.org/show_bug.cgi?id=18489 with xorg 7.3 - the system did hang in such situations (but there were no corruption).

DRM modules is kernel drm instead of libdrm. libdrm2.4.1 is OK. Maybe you can try on the latest drm module in kernel.
> Maybe you can try on the latest drm module in kernel. I don't mind to update it, but I could not find opensuse package in which it is located - is it somewhere in X11 repository (http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_11.0/x86_64/) or is it in kernel main package (kernel-default) or is it somewhere else? My current kernel version is 2.6.25.18-0.2-default - with latest updates available from package manager.
You can download the latest kernel from http://www.kernel.org/
Looks like the kernel delayed vblank swap bug that was fixed in the kernel back in July. Disable vblank synchronization in driconf to confirm.

I have DRI section in xorg.conf file, but no vblank parameters in it or anywhere else Section "DRI" Group "video" Mode 0660 EndSection
Try this set vblank_mode to 0 in your ~/.drirc, such as <driconf> <device screen="0" driver="i965"> <application name="Default"> <option name="vblank_mode" value="0" /> </application> </device> </driconf>

Bug was fixed in the kernel this summer, and we deleted the fixed offending code for 2.6.28.
