Re: Image tearing/image artifacts during video playback
I think you nailed it in one try. I had disabled a compositing manager, but not the composite extension.
sudo nvidia-xconfig --no-composite
to disable the compositing extension. I've just done it, and started watching again, and so far, I see no artifacts or tearing.
On a related note, I found some info on ubuntuforums advocating setting OpenGL VSync to Blank and enabling the TripleBuffer option. I'm wondering if those options will help/hurt the situation?
Also, I look forward to the issue w/ compositing being resolved. It's only eye candy, for the most part, but it'd be nice to have compositing enabled and still have good quality video.
Thanks for your help!
