Just found two minor bugs in the "world" sample. 1: it doesn't detect the LMB release outside of the frame, although it keeps changing the visuals if I pressed it within the frame. If I release it outside of the frame, it will need a further press-release cycle to free the mouse pointer. It might be intentional but could be annoying sometimes. 2: the snow fall appears linked to the terrain position in a strange way: hard to describe in my non native English; if you move the terrain around while looking at the snow flakes you get it.
