Public bug reported:
I gather this has been an issue for a long time, but I'm just running
into it now. basically, the nvidia binary drivers, no matter the
version, don't seem to properly handle vsync if you have 2 displays. no
combination of options seems to fix this so that it works correctly,
there's just always massive tearing in games and videos.
