Bug Description
On ATI Radeon HD3200 (Foxconn (Bengal) RS780 Integrated), compiz causes regular lockups (sometimes random) when it drives up cpu intensity. These locks are soon resolved after about 1 second or more or less. But always come back when cpu goes up.
top reports xorg drives up to over 80% CPU when firefox merely scrolls.
This only happens when compiz is enabled, not when fglrx itself is enabled. Compiz people said that it was a driver problem, so reporting here.
This is NOT AN INSTALLER ISSUE, it installs fine. Launchpad says there's no page xorg-driver-fglrx when I try to choose it for bug reporting.

the driving up cpu also happens in Opera and Epiphany, so it's not just a firefox issue.
