[Dmitry Pashkevich <1242207@xxxxxxxxxxxxxxxxxx>]

I did some testing and looks like the cause of this intense CPU usage is
Chrome's effect of "flashing" a pinned tab when it's updated (see a
short video attached). When I open this tab to make it stop flashing,
CPU usage of compiz drops down to 1-2%.

One would think it's a bug in Chrome but I'm not experiencing this issue
on another computer running 12.04 - on this machine compiz uses under 1%
CPU even when Chrome is open and has a flashing pinned tab. I'll try to
do some further investigation and report here.
