Ok, so that's a camera shot ?
Are you referring to that (blurred) ?
That is probably just too close to focus, or is not 'screen clicked' to focus.
It has nothing to do with the Vision System Error, which is probably the downward vision, though when this happens to others it normally says Downward Vision System Error (the VPS technology to hold position).
When are you seeing this ?
Do you see any code at all in pre flight info, like Error 40001, which is Downward Vision Sensor Error.
