This indeed works for the particular snippet I posted. However, I have a
more complex application where I am already using set-window-point, and
this does not fix the issue.

However, in the application for which I need this functionality, it
works completely as intended if I add (redisplay) between the calls of
set-window-point and set-window-start.

>From this, I get the impression that a pending redisplay may interfere
with reliably setting the window-start even if window-point is set!

All the best,
Markus
