It's a 'feature' that ships with the 169.xxx series of nvidia drivers
(and maybe 171.xxx) when using the opengl video renderer. I'm working
on it but haven't found a fix yet (though it could just be a bug in
the drivers).

Either try and roll back to an older nvidia driver or adjust your
playback profiles so that opengl isn't selected.
