Hi! I just noticed the same effect after a fresh ubuntu 12.04 installation. It was probably also the case with my previous ubuntu 11.10. In my case, compiz increases from less than 10 to above 70 % when I start thunderbird. Xorg is affected to a lesser extent.

I ran 'top', and watched the cpu usage around 20% usage, mostly the processes 'compiz' and 'Xorg' at 9% and 7% and 'thunderbird' at about 4%. I started closing other applications watching for a change, and when I closed Thunderbird the CPU usage dropped to about 6% at idle, with 'compiz' and 'Xorg' and about 2% each.
