You don't need that hack, you just need to use scroll_to_mark.

Scroll to iter *does* do exactly that. However, then the size of the
buffer changes and you need to re-scroll. So what you have to do is
save a mark which is scrolled to later.

If GtkTextView did the line heights synchronously it would be
slow. Very very slow.
