Karma Grip stabilization failure
The above is my video, shot yesterday at Winter Park. I'm the skier in it. This video shows horizon tilt to start, which is common from perusing YouTube.
It then shows what appears to be a new failure mode for the Karma Grip: the tilt lock fails in that the horizon, set manually to be a little high (pointed down since I'm skiing downhill), drifts down (pointed straight), then drifts far upward to the point of the camera hitting its lower stop and bouncing off of it repeatedly...
As the video title states, stabilization failure, GoPro.
