I'm sorry, but this doesn't explain your problem in enough detail.

First, what exactly do you mean by "scroll up the code"? which Emacs
commands did you use to scroll?  At least some ways of scrolling don't
move point.

And when you say "point moves across the window", do you mean that
point moves with the text or that the text moves, but point stays at
the same screen coordinates?  Depending on how you scroll, it could be
one or the other.

Next, what do you mean by "highlighting get recomputed as the point
moves across the window"?  What happens with highlighting as you
"scroll" that you don't like?

And finally, what would you like to happen instead in this case?
