I think it might be some sort of drunk filter? At least that's what I assume because many games do the moving / blurry stuff. Except this only happens on the map and nothing on my character indicates that I am drunk.

I think it is a bug. It happened to me a couple of times when travelling between carnage hall and villedor. Restart the game, it will go away.
