Here's a thing to try ( we should set non_disp_tiling in CB for > 128bpp formats) Makes UINT32 FLOAT32 work a bit better here. There's still some alignment issues at small mipsizes thoug

--- Comment #4 from Harald Judt h.judt@gmx.at 2011-12-21 02:34:25 PST --- I confirm that the patch helps with the problem. The textures start to look recognizable again, but parts of them are still displaced or corrupted.
