Vixia HF G50 Image Stabilization Randomly Stops Working

I picked up a refurbished Vixia HF G50 camcorder almost a year ago, but for several months I've noticed some of my footage looks quite shaky on my tripod, even with dynamic (optical) stabilization enabled. I always thought my cheap, flimsy tripod was the problem, so I recently got a new one hoping that would solve the issue, which it didn't. The stabilization works flawlessly for several seconds at a time before randomly disabling itself, and I have to move or shake the camera to get it working again, only for it to disable again right after. I've double checked my settings and done a factory reset with no luck.


Here's an example:


dynamic stabilization was selected in settings the while time.
