(BGE/UPBGE) Strange camera shake during the game

[Trample-ingame]

for the twice i’m having this problem and i don’t understand how to solve it, the POV camera is parented to an empty parented to a bone of the player head, during this animation the player bone to move the full body is copying the location and rotation of a bone of the husky in his mouth, as you can see if i start the animation in editing everything works fine, but during the game the share is impressively annoying. i even tried to run the game with animation setting at 10 instead of 30 but the problem persists!!!

Could someone help me solving this issue please?

I tried parenting the camera directly to the player eyes bone but nothing, tried moving the animation of the player one frame after but nothing, tried to play the game in blender 0.3a but it crashes when switch to the POV camera in the game!!

Can you try disabling all the physics on all your objects (no collision)

[Trample-ingame]

there isn't any collision, it's all animated

Can you provide a test file? Also, how big in terms of scale (transform coordinates) is your scene? May be a discretization problem.

this is a screenshot of the full scene and that action in a new file importing models-armatures-cameras and the problem persists even if there are only these two character in the scene BBG test-camera shake.blend.zip
