Hi,

Please close the duplicate in Desktop software, not here, as there are more viewers here. thanks...

Problem:

When I drag windows, or when I play movies, there is always page tearing (windows seem cut in half).


My System:

openSuSE 10.3
Nvidia proprietary drivers
compiz/xgl

I have __GL_SYNC_TO_VBLANK=1 set as environment variable, and the following is my xorg.conf, yet problem still not solved:

help anyone? :P

Apparently that's a new one to everybody, but I'll give it a whirl.

The first thing I found was an updated driver for the GeForce 8500 GT, released 12-20-07, that corrects a lot of problems with X-rendering, stability, Compiz VT switching, and more.

Go here to install newest driver. There's also information on how to find and report bugs to NVIDIA.

Hope this helps...

thx for the info.

I already tried the latest drivers, but it didn't help. Tearing is definately present in video playback with compiz on. The nvidia settings won't work with compiz on. With compiz off, the nvidia settings work, and then vertical synchronization can be selected for both xv and opengl. The tearing then stops in media players, but the overall tearing of windows remains.

From what I read it's an outstanding and complicated issue that is well known and won't be solved for some time. It requires big changes to the underlying x/nvidia architecture.

I don't know to what extent the problem is with ati drivers.
