When running along in the forest on the side of a hill, if the Sun or Moon is on the other side of that hill, your character still casts a shadow despite the hill being in the way of the light and as the surface below you is correctly not casting any shadows, this results in floating shadows on trees and objects. I've attached screenshots displaying the issue, which is something I noticed in Arma 2 as well. The final screenshot 00022 probably shows it best. {F28310} {F28311} {F28312} {F28313}
