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. Also, it doesn't seem to change, despite of application changing contents of its window. I tried some more changes in the alignment table (like multiplying related alignments by two), but it had only negative effect.
