i also saw that, with moving mouse cursor on a radeon 7000/VE.
since i read about it happening when opening windows (for me it happened several times when switching workspaces, i'm using the wall desktop plugin for that, but maybe also a window was opening in the background, not sure), and since some people mentioned that increasing AGP aperture helped, i thought it might be too little texture memory to store all the windows? I tried increasing my AGP aperture in the BIOS (from 64 to 128Mb), I'll see if it helps.
