Don't know if this is considered a "technical issue" - but there's a problem with almost-invisible fire surfaces.
I can't say what causes them (they usually appear after a fight - so maybe fire spells, or poison+fire), but they are DEADLY and almost invisible.
If I zoom-in a lot I can see some transparent colored "waves" coming out of the ground, and maybe a bit of white smoke, but when zoomed-out (my default mode) I can't see them at all. This forces me to Quicksave at the end of each battle before I even start to move to pick things up.
Rain doesn't seem to put them out.
