vertical syncronization (double buffering) not working
Hi,
My System:
openSuSE 10.3
Nvidia proprietary drivers
compiz/xgl
When I drag windows, or when I play movies, there is always page tearing (windows seem cut in half).
I have __GL_SYNC_TO_VBLANK=1 set as environment variable, and the following is my xorg.conf, yet problem still not solved:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder26) Wed Sep 12 14:29:17 PDT 2007
