The issue appears when margin scroll-margin is different than 0

What is weird?  (I cannot see anything in the video you posted.)

Don't you see how the screen is jumping up multiple lines? It should
go up one line at a time when I scroll upwards.

add this:

    (setq scroll-conservatively 101)

and it should always scroll by one line a time

I see nothing, just a black rectangle.

Is this in `emacs -Q`?  And how do you scroll, with what command or
key sequence?

How long did you take to produce that code?

I bet it would take me longer to make that code.

I set mine to a million so I can scroll conservatively indefinitely.

It doesn't matter if you use 101 or a million:

>If the value is greater than 100, redisplay will never recenter
point, but will always scroll just enough text to bring point into
view, even if you move far away.
>
>A value of zero means always recenter point if it moves off screen.
