when using fglrx unity does not display and slow moving windows

view story

http://askubuntu.com – two issues when using the fglrx driver: when i move to the propriety fglrx driver, unity does not load the side bar. the login screen loads (with top bar displayed), but when logging in, the unity side bar does not load. i can right click the desktop and create new folders. i can ctrl+alt+delete and manage to get to system settings (where i can change back to open source driver). any ideas? other issue: when using the fglrx, when i open a panel say system settings), and move the panel, it lags, it moves at like 2 fps, instead of being a smooth move such as when using the open source driver.
