After playing with mesa/src/gallium/drivers/r300/r300_texture_desc.c (see attached patch), I was able to get things rendering properly -- font issue disappeared with setting 'height' alignment of 8bpp textures to '2' and misrendered artifacts on some round edges with 32bpp textures and 'height' alignment to 2. Patch contains only values I needed to fix -- I guess there is some relation between parts of array I've been modifying. Unfortunately, this patch causes, that some (random) of GNOME 3's popup windows are being rendered improperly -- their content looks like portions of other textures (e.g. desktop background, icons, ...; random parts of vram), with no apparent relation to expected content.

Not true. The r300 driver gets it right for all the other GPUs, it's just rs6xx that is broken. Please try the attached patch.

I tried this patch; unfortunately it just reverted the old behavior -- problem with certain surface sizes was gone, but problem with texture alignment returned for both 8bpp and 32bpp textures. I did not notice any other differences. If you will have any other ideas/patches, I'll gladly test them; but I can't do much here by myself.

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.

UPDATE: looks like some fonts are not rendered properly either, but I can't justify whether they are rendered into 8bpp or 32bpp textures.
