Description Nico Kruber 2015-08-04 11:57:24 UTC 
In several more complex and huge page dimension pdf files, okular fails to re-render contents of the screen if I zoom in or move the shown area when zoomed in. New (previously invisible) areas stay white; zoomed-in areas have a bad resolution. Refreshing the view with F5 renders the areas correctly

Reproducible: Always

Steps to Reproduce:
1. open the pdf file (attached in comment 1)
2. zoom in, e.g. with CTRL+mouse wheel, to 400%
3. see that the image does not get rendered with a higher resolution
4. refresh (F5) -> it renders correctly
5. scroll horizontally to the right until a white area is shown and wait
6. this area is not re-freshed until hitting F5 ourselves

This works fine for me on Okular shipped with KDE Applications 15.08 Release Candidate (aka 0.22.90) please reopen if you update to it or a newer version and you still have this issue.
