Somehow the tree animation is broken in the tilesets:
Use the tileset birchforest and start a game in map conflict with all players in team 1.
Look at the birches which should move in the wind.... compare this to 3.9.1 ( to see the animation effect, animated tileset objects must be enabled in the option ).
Update: It turned out that the tree animation was broken because I compiled with clang. Using gcc all is ok !
