Nikde jinde se tenhle bug neprojevuje, protoze jde o specialni pripad kdy je pouzivan jak fetch4 tak i 24bit DST. Je to vyjadreni primo od ATI.

They said that the image problems are caused by a bug in the compilation of the shadow shader on the Radeon X1900. They explained that this shader is different than the one used on either the the X1800 or the GeForce cards because it "employs both Fetch4 and 24-bit DST" in order to best take advantage of the X1900's capabilities.
