In this picture, http://i.imgur.com/VTsP57B.jpg you can see the graphical error. I forgot to turn my UI off to take it, but as you can see, in the mist, there are small dots of white all over, mixed in with streaks of the proper graphic.

I believe a friend of mine called this artifacting, but I'm not sure, and when I've looked it up I've not found a case of someone with the same bugs I've been having.
