The issue does not happen with metacity or mutter, it only happens with compiz, with or without unity enabled.

Assignment Sam although he is busy(or about to be) with exams I believe just assigned so that he is aware of the problem

I'm off exams.

The problem is that we are doing shadow clipping in compiz in a rather
inefficient way which is causing a lot of CPU usage on some systems. I have
a branch which optimizes a lot of this, though I noticed from profiling that
we are still doing a lot in the wall plugin so I'm going to look there also.

I have very slow Ubuntu, I do use allot of Compiz plugins and 11.10 is unusable. scrolling and window dragging etc is too slow.
I use TwinView through proprietary Nvidia Drivers.
Gnome Shell I.e. with Mutter is much better
Has this been fixed?
