Ah yes... you are totally right of course.

So for the first question, (pdf-scroll.el is not required indeed),
do `M-x papyrus-demo`, maximize the demo window,
then scroll down a few pages, and split the buffer horizontally.
Now, the page in the other window does not get diplayed.

Then do `M-: (print "test")` and hide the echo-area by pressing
`esc`. Now the page does get displayed.

So my question is how can I achieve this without printing
something first.
