I have no tearing on GL in fullscreen.
I do, however, have tearing for very simple GL code in windowed mode (fill window black, flip, fill screen white, flip - tearing is painfully obvious), mplayer -vo gl in both windowed and fullscreen mode (since its "fullscreen" is actually a screen-covering window and doesn't trigger the same mechanism), and mplayer -vo xv in all modes.
This is with all compositing turned off *and* using a window manager that doesn't support in anyway, by the way.
vaapi might possibly work, but mplayer doesn't support it. (I know about the mplayer-vaapi patch; it hasn't worked with modern mplayer(2) code for some time, sorry.)
