I do see the same issue as you when performance drops - windows move
'jerkily', by not moving with the mouse and then suddenly jumping a
large number of pixels all at once. The worst I have seen it get is that
the mouse will move and the window not at all until a second after the
mouse stops moving.

I use glxspheres because it provides numbers to describe the drop in
performance. Typically glxspheres has much lower fps at the same time as
the desktop becomes sluggish so I assume they are related.

I originally opened bug #861061 when the drop in performance had
apparently become permanent, ie persisting across reboots. At some point
it automagically resolved itself but has returned a number of times
since. I suspect they may be the same bug but Daniel says is
experiencing a permanent drop in performance and wants to use 861061 to
track this permanent drop in performance.
