In fact, all of a sudden, the onboard fxp(4) (which I don't use) shows exactly the same behaviour (and I have seen this happen the nVidia driver as well). This makes me believe the problems is elsewhere, and not in emu10k1/emu10kx at all. I will update my machine to the latest CURRENT and see how that goes. Could the recently-added MSI changes perhaps contribute to this odd behaviour? It looks to me either my machine is broken (even though Windows XP works fine on it), or something changed in CURRENT.
