Research direction
Reproduce the slowdown in Xreader 2.8.3 on Mint 20.1 Cinnamon using The Greek View of Life and Organic Gardening, comparing opening and scrollbar navigation times. Investigate why the first PDF is slower despite being smaller; done means opening and view refresh times are considerably shorter for documents of that type.

Description
* Xreader version 2.8.3
* Distribution - Mint 20.1 Cinnamon
Issue
Xreader is slow to load and to update the view with certain book files. This does not seem to depend solely on the size of the file, but some other formatting property.
Steps to reproduce
- Download The Greek View of Life from the Internet Archive (16.2 MB).
- Open it and when open, use the scroll bars to scroll to another page, say, half way through the book.
RESULT: The app. takes a long time to open and update the view.
- Now download Organic Gardening (22.6 MB).
- Open it in Xreader and again use the scroll bars to navigate through the document.
RESULT: Even though the latter book is considerably larger it opens very quickly.
Expected behaviour
Opening and view refresh times should be considerably shorter for documents of the first type (above) than is currently the case.
