Well done on getting so far so fast with so little trouble.

I've only been able to skim your latest video so far because I am about to go out for the day but I have to say the display looks rock steady to me in the segments I looked at. If the display is occasionally shifting up or down by a line or two it may just need a small tweak to the hold controls in the monitor, but don't go there until we have a better understanding of what you feel the problem is.
