I tried it now, and it's a lot more consistent now than it was before. Before it was almost always off by one line, but now it's correct most of the time. I tried this on something that has more dramatic line height differences, and the phenomenon is more noticeable there -- when scrolling downwards, things are very predictable, but when scrolling backwards, Emacs seems to decide to scroll a couple of screenfuls when there's large images in the buffer, and you have to C-v twice to get back to where you were.
