--- Comment #10 from Alex Deucher agd5f@yahoo.com 2010-08-29 14:22:07 PDT --- Only D16 and D32 depth formats can be blitted from directly with Z compression disabled. D24 and D24S8 formats require a special blit to a new buffer, and then you can use the new buffer as a texture source. Unfortunately, this is kind of hard to deal with the way classic drivers are structured.
