Nondeterministic ball bounce[SOLVED]

edit

Hello,

I am getting different behaviors with exactly the same execution and world settings. As you can see in this video , I reset the world every time and launch the ball with exactly the same velocity. This happens when launching the ball against any kind of surface (not only this board).

Update: more videos: vid2, vid3.
