Operating system and graphics card
Broken: (all, i think)
Short description of error
Animation of some constrains don't properly baked
Exact steps for others to reproduce the error
I upload blender scene and video capiture that you can see a delay between moving parts of objects.
It's happened, when i bake (of simply play animation) bones with constrains like Damped track.
In render (processwithout baking) it's not happened.
Hope you can fix it.
