Using EXA is nowhere near a proper fix. To see what I mean, open FireFox and attempt to scroll a decent sized page; the CPU will spike to 100% usage and FireFox will drop to a crawl.

A few of us from ArchLinux are having this same issue, with the card "ATI Technologies Inc Radeon Mobility M6 LY". It is *not* related to Compiz in anyway, my notebook runs a small/lightweight wm called awesome, and has never seen compiz.

For us, downgrading to xf86-video-ati-6.12.4-3 and using XAA is the only "proper" fix. See our thread about it here: http://bbs.archlinux.org/viewtopic.php?id=94960
