I've been struggling with what seems to be the same bug.

Summary: When I log in, compiz and all my programs run ridiculously
fast. Over the course of the next 30 hours (give or take), it gradually
become sluggish and jerky. If I log out and log back in again, then it
goes back to being fast.

Details: It's a nice, new, sexy computer. i7-2600K Sandy Bridges
processors, 16GB RAM, SSD, GeForce GTX 570, current NVIDIA driver, dual
screens with twinview, running Ubuntu 11.10 with Unity.

When I log in, everything runs really, really fast with beautiful
graphics. Gradually, things slow down (after maybe 6 hours). Programs
which rely on OpenGL and normally use ~15%CPU will start using 100%CPU.
Temp never exceeds 52 degrees F though, and RAM usage is low. Video
memory usage stays low. No swap usage at all. My window switching
becomes very choppy. To fix everything, all I have to do is log out and
log back in. But 7 or 8 hours later, the same issues pop up.  Reverting
to Natty doesn't help at all.

I first noticed this problem while using the graphics intensive program,
VMD. But the problem is definitely not limited to that program. I even
experience choppy window switching when I have no programs open. I've
tried a billion things, but nothing has remedied the problem yet.
