little experiment
(In reply to comment #13)
After more thorough testing, it seems that r300 driver is not able to correctly create surfaces of certain dimensions; random vram content is shown instead.
Not true. The r300 driver gets it right for all the other GPUs, it's just rs6xx that is broken.
Sorry, I was generalizing too much; for me it's always in rs600 context.
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.
