This will be a lot of work.  I really hope we can avoid it.

What I am seeing is what one sees for any window showing a sufficiently
large buffer after evaluating something like

  (setf (window-start) (+ 10 (point-max)))

and I have clearly shown that exactly that is what the code potentially
does.  I really don't want to spend half an hour to create a recipe
until you at least think about what I said.  I'm a big fan of recipes,
really, but in this case I would have to prepare a complete fake org
file with dozens of fake entries corresponding to suitable finely
composed dates ... this will take unnecessarily long, can't you please
just think about what I said?  Five minutes?  Please.

Does restoring the result of (window-start) from the old agenda view, as
a plain number(!), always give good results in your case?  What happens
for you in the scenario I described, when (window-start) of the previous
view is larger than (point-max) of the new view?  Emacs can't do
anything but to show nothing when the end of the buffer lies "before"
window-start.  No?
