That's probably the same issue as http://bugs.winehq.org/show_bug.cgi?id=18794
I'm afraid the conclusion there is simply going to be that fglrx's FBO
support sucks. We could probably justify not checking depth stencil
formats, but it's perfecly reasonable to try
GL_COMPRESSED_RED_GREEN_RGTC2_EXT. The driver should of course crash
on neither of those.
Hmm. Does fglrx support this extension at all? I think fglrx has
GL_ATI_texture_compression_3dc, which is essentially the same, but
uses GL_COMPRESSED_LUMINANCE_ALPHA_3DC_ATI.
Besides that, I don't think I have ever seen renderable compressed
textures anywhere, so I'd say it is reasonable not to test it either.
Still, the driver shouldn't crash.
