Summary: OpenGL is distorted on SiS
Product: Mesa
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Drivers/DRI/SiS
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
When I start a OpenGL app all polygons seem to have one edge locked at the top
left corner (0,0). However this only happens with objects having a depth
(z-component). GLSlideshow for example works fine. Every now and then there is
one frame that is partially rendered correct. I used GLForest to test this ..
Here the info about my setup:

This is a Elitegroup Desknote A90/. I tried the SiS-driver from the Xorg release
and the binary driver sis_drv.o_xorg_gcc3_200804-1.tar.gz from winischhofer.net .
