Map icons for trees, bushes and rocks are duplicated. Trees (and bushes) appear as black or dark gray colored, they also disappear in the upper part of the map view (see the video below).

Many people do not have this issue which would suggest its something on my system, I get this on two different computers. Issue is not resolved by reinstalling arma3 and deleting all bohemia user etc settings directories found on on C: and launching arma3 without any addons or even existing profiles directory (steam -> arma3 -> play game -> a3 launcher -> PLAY).
