Confirmed.
The problem occurs with ATI Radeon HD 4250. Everything is really choppy even with sync-to-vblank off and all those fixes enabled in Catalyst Control Center (described above). Tested both on repository-native drivers and 11.5 from the producer's website.
The open driver works very well with compiz+unity. It doesn't support fast acceleration in games though.
