I also experience this problem, with 9.10 installed on a Dell Inspiron 1525 laptop with Intel X3100. i tried using the desktop (especially when trying to open/close new nautilus windows) without AWN, and performance was way better, as animations were smoother than ever.
uploading AWN again, and the problem returned. Although, i'm certain this is not an issue regarding AWN devs. alone, but a compiz issue with intel drivers in general..
