What version of windows are you running? This is the first time I see this shader giving problems :/
Windows 7 Home Premium 64 bit - it's an old HP laptop with a built in Intel HD Graphics chip. DirectX 11.
It's as soon as I enter a new doorway. I tried deleting the folder in Windows Explorer that belonged to the doorway, and the game would then load with me in that deleted folder as a tiny room with nothing really in it. I could then walk back to level 1 (C:) - however as soon as I try and walk into a new doorway, the same shader bug occurs.
I wrenched my file to get out of that folder room. Tried a different doorway and it led me to a grassy outdoors place that worked fine. However the next doorway I tried inside that one (from level 2 to level 3) crashed me with the same shader issue. Perhaps it's just certain themes/backgrounds?
