Re: Redisplay issues with 'space' display properties on overlays

[dalanicolai]

So my question is how can I achieve this without printing

something first.

This works without the printing in Spacemacs/Doom Emacs, but

I don't know which thing is responsible for the different behavior.

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.

And then do what? look where? for what issues?

I don't understand.  It is your code that inserts the overlays which
AFAIU give you the problems, right?  So I think it should be possible
to construct a simple test case using some image file instead of what
pdf-tools produce.

I don't think I understand the situation well enough to answer, sorry.
