<pre>That's a known issue, it's a design problem of DRI2.
Essentially there is no global time you could return from
VdpPresentationQueueGetTime. Instead what you return is always the an
estimation based on the vsync counter and that's unfortunately per output
instead of global.
Additional to that I never bothered adding the difference between the last flip
and the current time to the result of VdpPresentationQueueGetTime. So when you
don't have a page flip the result of VdpPresentationQueueGetTime will probably
stand still.
