I am using the Radeon driver with a Radeon Mobility M6 LY card, and similar artifacts sometimes appear on OpenOffice and when viewing large pdf documents. AIGLX will give a list of warnings and then will load: (WW) AIGLX: 3D driver claims to not support visual 0x30 (WW) AIGLX: 3D driver claims to not support visual 0x31 (WW) AIGLX: 3D driver claims to not support visual 0x32 (II) AIGLX: Loaded and initialized /usr/lib/dri/radeon_dri.so (II) GLX: Initialized DRI GL provider for screen 0 I've just learned to live with it (since I haven't found a solution yet). -- Regards, Mick
