Yes, we are experiencing that also. I believe that it is from the servo trying to return to the position you tell it to. How is it mounted to your test robot? We have it on an old robot with tape, and since that isn't as sturdy, it gives a little. Thus, the weight of the camera moves the servo around more than it wants, and it continues to over-correct. We can stop it from jittering by holding it in place.
