I could be wrong, but it kind of looks like the bump mapping lighting (or some other lighting; are the floor and woodgrain geometry or normal maps?) is blasting out the color on almost everything. I’m suspecting bump here because your grey-with-bricks wall texture looks fine on all surfaces, and the round emblem on the wall look fine, but everything else seems to be full black or full white.
If you are using normal maps (and assuming you have access to a machine with the bug or someone who does and is willing to test) maybe try pulling the normal maps off something and checking whether that thing starts rendering correctly…
