Seems similar to this thread https://forum.dji.com/thread-36948-1-1.html .
I have the latest firmware and app.
Here is a video of the twitching in action:

Purchased recently. Did I just get a bad piece?

I have set a path for it , but the twitching seems too much compared to the amount the camera moves. It must take a lot more battery than necessary and heat up the device.

After every snap, the gimbal will twitch. It has always been doing it with mine and seems to have no affect in the images or smoothness of the rendered time lapse.

Good to know for future use.
