Latest version? Patch 1.091? Clean install? Tried clearing your gfx cache?
Latest version, and been having this problem since 1.9 and 1.33.3 were out. Clean installed. Clearing the gfx folders in my docs and the steam folder both didn't work. Steam cache integrity check has also failed to solve anything.
The weirdest part is that on GoT (which isn't really that fun), and vanilla, this doesn't occur at all.
