I also appear to have the same issue on: HP Compaq nx7010, with 2GB Ram, and an ATI Mobility Radeon 9200 video chip.
Was fine with 8.10 Did automatic upgrade to 9.04 and whole system now seems very slow. Maximizing, minimizing, opening, closing, etc., of windows knocks the system out (system wide, not just that window) for up to a few seconds. Video is unwatchable... even with Compiz turned switched off (using compiz-switch). Video image can't render fast enough so becomes very jumpy, lagging behind, rendering in patches, etc. That was tested on VLC... whilst always ran fine on 8.10 I am glad to see this is not an issue just with my computer, and look forward to hearing of a solution.
