Changing Capsule Collider radius

Unity Engine
1

When i increase the radius of a Capsule Collider when the game is running my object moves up in the y.

		if(Input.GetKey(KeyCode.LeftArrow))
		{
			speed -= 1f*Time.deltaTime;
		}
		else if(Input.GetKey(KeyCode.RightArrow))
		{
			speed += 1f*Time.deltaTime;	
		}

		speed = Mathf.Clamp(speed,-1,1);

		CapsuleCollider cc = GetComponent<CapsuleCollider>();
		cc.radius = Mathf.Lerp(0.2f,0.5f,Mathf.Abs(speed));

As the radius increases the object moves up in the y.

To fix this i have to subtracted from the Capsule Collider height

The height of my object is 2 and the radius moves from 0.2 to 0.5 depending on speed

cc.height = 2.0f - ((cc.radius-0.2f)*0.1f);

This makes the object stay on the ground.

Is this a known bug or am i missing somthing?

Cheers

I have encountered possibly the same issue. When changing the radius of a capsule collider in runtime, it somehow affects the height even if the height value is unchanged.

Have you found the issue?

Yes!! I can confirm this, now that you we have the physics debugger we can see this bug happening!
UP!
