Ok, so what about C-n / C-p ?

It seems like something is causing unnecessary redisplays / recentering.

What is the value of the variables timer-list and timer-idle-list ?

A lot of efforts have gone into making Emacs 22 scroll images in a
_reasonable_ way (not perfect, but much much better than Emacs 21).

But if code that displays images (such as w3m seems to do) does not
use Emacs' line move and page scrolling functions, such code must
do the hard stuff itself...

Since w3m is maintained outside Emacs, you can hardly blame
Emacs itself for w3m not doing the right thing with respect to
image scrolling.
