  I tested gnome-shell with it; when using alignment table patches (Xorg's ColorTiling was always false), there was no change. However, when I reverted to original r300_texture_desc.c, things seem to work more-or-less correctly -- 8bpp textures seem to render fine (there's one case when I'm not sure), however, small 32bpp textures still render incorrectly.
