Bug Description
In Ubuntu Natty, Unity needs Compiz and OpenGL, and OpenGL needs composite on, which leads to serious GL flicker when using mplayer watching videos in fullscreen mode through GL output. Switching to xv output the mplayer works just fine, no flickers.
I'm not sure this bug is due to unity, or compiz, or the GL driver. But I am quite sure in the previous version of these projects, with no composite on of compiz, the GL output works fine for mplayer. And I don't think developers have considered the possible consequence of forcing composite on in Compiz.
Please don't tell me the workaround such as giving up trying gl output and turning to xv output. GL output of mplayer is far better than xv output with more speedy video rendering and prettier osd & subtitles.
more of a compiz/driver bug so moving to compiz for now, might be helpful if you disable 'sync to vblank' and check if that is of any help
