I have had similar on the inspire with the X3 camera on.
From what I could work out myself. The overload warning causes the gimble to switch off witch would explain the camera motion.
Mine stopped working thereafter.
The only fault I could find on mine was the ribbon wire inside the gimble mount had been crimped at some point possibly at manufacturing phase and hadn’t effected performance until this point.

See images on this thread, I put it back together expecting to have to source a replacement ribbon and (touch wood) I have not had a problem since.
