Re: Tearing with vdpau even though composite is disabled
Could you please try the latest driver; 256.53. There have been some bugs and resource leaks in previous versions which might cause your issue.
If that doesn't solve your problem, or you can't try a newer driver, can you please run the following commands:
mplayer -vo vdpau somefile.xxx
... and paste the resulting log here. That will hopefully tell me why the overlay presentation queue isn't being used.
