Visual Bug - related to Flashing Colors?

Saw this once in a Vault Map, black 'walls' across all parts of the screen, changing depending on where I am. Perhaps related to the shadows in the map?

I have had flashing colors in Phantasmagoria and elsewhere, but this was totally different.

hehe, that was kinda cool but yeah, it happens, shadows freaking out, graphical issues are to be expected. Every new content update brings new weird stuf. As long as they are not permanent I shouldnt worry bout them, they come and go. Wacky shadows, floating carts, black boxes, strobe maps, laser golems, u name it... put spotify on and go wild ;)
