(Get the code!)
I'm on ubuntu precise with compiz window managing.
So if I'm reading correctly, on newer versions of QT it should be possible to have a single thread whose job it is to wait for vsync and then a signal back to the main gui thread when that happens? So swapinterval would still be set to 0 but the timing of the calls would be driven by that vsync signal instead of the current qtimer. If that's the case, could we fall back to the qtimer for older versions of QT and just let there be tearing? The coding difference between the two shouldn't be too much in that case.
