The same architecture (bigEndian) shows no this specific issue on PowerMac G5 Quad with PCI-Express ATI Radeon HD4670 with VGA BIOS (not powerpc flashed card). The problem seems to be a screen changing resolution or similar having Compiz activated. If I switch the screen resolution on this laptop, the garbage on the screen is more visible than using NO COMPOSITE Marco Mate Display Manager. The problem is enhanced using a second monitor attached to a DVI connector on this laptop. Can be easly reproduced.
