The padding is applied to the canvas, so you will not see the padding at the top or bottom unless you are scrolled all the way to the top or bottom.
You can workaround this by putting the ScrollingFrame inside a normal Frame, and applying the padding to the Frame instead.
That’ll preserve the padding regardless of scroll position, but your scroll bar will be offset from the edge as a result.
In regards to your OP, the reason the padding changes is because you’re using scale instead of offset. Ideally, padding would not change depending on screen size.
