It looks like this isn't hardware specific but would happen with any DRI based 3D driver. libgtkglext1 seems to attempt rendering to GLXPixmaps without properly checking that they're supported (IIRC they're only supported as of GLX 1.3). -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer
