It could be selection requests...

One thing which can confuse Emacs to make superfluous redisplays is
the clipboard/x-selection.

Some buggy clipboard handlers will query the "selection owner"
(e.g. Emacs) very often for the contents of the clipboard/selection,
and Emacs doesn't always handle that well.  (Another effect of this
that I see myself [I use RedHat 9.0 which has a buggy KDE Klipper]
is that the blinking cursor disappears for several/many seconds).

Before you scroll the image window in Emacs, could you try to select
some text in some other application (e.g. an xterm), so that the
selection is not "owned" by Emacs.
