Re: video tearing when composite is enabled
This bug (xvideo and opengl tearing) does not occur after these steps:
Put the mark to sync to vblank in nvidia-settings (xvideo and opengl) and compiz.
-open compizconfig settings manager
-uncheck the "detect_refresh_rate" in displays settings
-change refresh rate (for example: from auto to 60Hz or from 60 to auto)
-check the "detect_refresh_rate" in displays settings in compiz.
After these steps, everything is working well.
