It does not make the problem go away for me: it does improve it though:
instead of no screen redraws at all, the screen redraws about once every
3 seconds instead. As with vsync enabled, glxgears constantly claims
that is it doing 4000 FPS. So I don't think this really fixes the
problem at all, it just removes some, but not all, of the xsync calls
causing the problem.
