I think we also have made different guesses of what is most important.

The bug with clip_changed is not very subtle in my view. It is just a
bug in the logic, a bad assumption that was not noticed before.

There seems to be something interesting there then. Fine.

I can't see any recentering at all (except for those connect with the
visual-line-mode/word-wrap bug I also told about) but Emacs was
recentering very often for me when holding down <down> before I wrote
my patch for clip_changed.

Thanks. I will send them to you privately then.
