Dear David,

Thanks for looking at this. I checked, and smooth scrolling does not matter.

Here are four screenshots using a random example PDF I found here 
https://juventudedesporto.cplp.org/files/sample-pdf_9359.pdf

To interpret the file names: old is 20.12.3, new is 21.08.0. The four 
numbers are as follows:

1) after opening Okular, loading the PDF from the command line

2) after pressing Space once (now we're on the bottom of page 1)

3) after pressing Space once more (now we're on the top of page 2)

4) after pressing Shift-Space. now we're either on the top (new) or 
bottom (old) of page 1.

I'm using Plasma on X, not wayland.

The fact that you cannot reproduce it makes me think it is a dependency 
issue. I noticed that upgrade/downgrade of okular pulls in a matching 
version of libokular5core9, and changes nothing else on the system.

Cheers,

Wouter
