Counter-Strike: Global Offensive - Constant Hitbox issues

In response to 3kliksphilips challenge to find repeatable hitbox problems i give 2 while crouching and jumping.
1. Crouching: The server does not seem to play the crouching animation and rather instantly switches from standing to crouching, I didn't test from crouching to standing just thought of that.
2. Jumping: the server hitbox looks like the server just moves the players standing hitbox up while jumping and lower then the actual play model.
Valve, Please fix!
