Steven, could you please be more precise on how should I configure my Xorg installation and what is the exact commandline to use when running Unigine Heaven benchmark to spot the performance issues you had reported? I also use dual-screen setup at home and used to use nVIDIA TwinView (a.k.a. MetaModes) tech to get desktop spanned over both monitors. Should I reconfigure my installation to use Xinerama to reproduce the bug?
Yes, Xinerama seems to be the needed to trigger this bug. As for the Unigine commandline arguments, I'm not sure about the exact command line, but I'm sure it was something simple if just running the binary doesn't give the desired results. Certainly nothing fancy.
I cant reproduce right now as I'm running nouveau drivers, due to an incompatibility between xserver 1.11 and the nvidia 275 drivers (current Debian testing). I'm not to keen on installing the drivers from nvidia directly as I always needed to reinstall them after a kernel or X upgrade and I'm to lazy to downgrade the xserver. Although I'm eager to try out the 285 driver (currently in Debian experimental), I'll do so as soon as they go into testing.
That said, the clue is definately xinerama, twinview does not appear to be affected, neither are separate x screens or single monitor setup. Should you be unable to reproduce, I do have to note that both monitors have a different resolution (1248x1024 and 1024x786), but I don't really think this matters.
