Default Tearing in every video player when composite enabled

Hi
As anyone knows there is a problem with tearing when composite is enabled. When I disable it in xorg.conf, video tearing is gone in 100%. The problem is that I want to have it enabled.

I tried almost every solution found on this forum, but still, the problem appears. Please can anybody help me with that ? Or maybe it is impossible to get rid of tearing when composite is enabled. And also, I'm not using compiz, just metacity with effects.

Here is my xorg.conf
Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 256.53  (buildmeister@builder101)  Fri Aug 27 21:34:01 PDT 2010

The metacity compositor uses XRender and it's currently not possible to avoid tearing with it. You might have somewhat better results with Compiz, if it is correctly configured.

What a pity . I really like simple metacity with effects. Well, maybe in future releases of nvidia drivers it will be possible. Thanks anyway.

This is not a problem with NVidia's drivers, but with the way XRender works. You will see tearing with all drivers.
