Same here. I tend to look at everything PoE-related through rose-coloured glasses, but that's a bit much even for me.
In buildings the pink squares appear in place of the fire effects, as for the outdoors, refer to the image above. I'm going to take a look at my videocard's drivers next.
EDIT: Nevermind, I was just being stupid. There are two patches, one for the basegame (~80 MB), the other one (~175 MB) for the expansion.
