After more research, this is seeming more and more like a compiz bug. While the nvidia driver also seems to have problems and it certainly isn't helping things, Gnome 3/Mutter and KDE/Kwin do not appear to be affected. As I mentioned in comment #40, KDE is slower for me than Gnome, especially on dual displays. However, I think this is a limitation of my hardware and KDE because the slowness is uniform and consistent. glxgears reports lower framerates, but it is smooth. I think KDE stresses my system more than Gnome and adding a second display increases the strain. I hope this helps to narrow down the cause.
