[Bug 1307144] Re: 'unredirect fullscreen windows' causes tearing


I'm sorry for triple-posting, but to summarize the end of my previous
comment: "Allow Flipping" in nvidia-settings > OpenGL Settings does
completely eliminate tearing for fullscreen, unredirected output for
OpenGL GLX output in vlc. It does eliminate, or affect tearing for the
XVideo output method. So it will probably help for OpenGL games.

There is still a minor amount of tearing, maybe one frame in 30~100,
even with OpenGL output and flipping enabled, when redirected by compiz
(not fullscreen). It seems the only thing that prevents this is the
"Force full screen redraws (buffer swap) on repaint" option... ok but
actually, as shown by the "Show Repaint" plugin, that was because there
was another vlc instance behind several other windows, that was paused
and therefore causing repaints.
