I have reproduced the problem with the PPA version of compiz. It was
*much* harder to reproduce it with the PPA version, though.

I think it might be related to memory stress - my system ran out of RAM
and was using swap heavily, glxspheres dropped to around 40fps, and
compiz was only reported as using 31MB of RAM instead of the more normal
120MB. Killing processes so that RAM usage returned to normal didn't
help, though. (Currently the system is showing 37MB of swap usage.)

Restarting unity and then compiz didn't help - in fact performance
dropped to 30fps, although compiz was again using 120MB. Logging in and
out also didn't help (still 30fps).

Restarting lightdm made performance go back up to 40-44fps.

('Force sync between X and GLX' doesn't help, either. But the jerky
windows movement must be a different issue because it occurs
independently of the glxspheres slowdown - I don't have jerky windows at
the moment but I do have the drop in glxspheres' fps.)
