While doing a long 8 hour session, I must have got hit with an ice attack or something, because I was covered in what looked like frost. The problem is that it never went away for over 30 minutes. Sometimes if I switched weapons, the effect went away, but I still was covered after death and respawn, and when it did go away, if I got hit again or I hit an enemy, I became covered again. I exited to the main menu and went back into the game and I was still covered so when I completely closed the game to desktop and came back, it was fixed.
