            Bug ID: 391972
           Summary: okular slower than evince at rendering a pdf
           Product: okular
           Version: 1.3.3
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: PDF backend
          Assignee: okular-devel at kde.org
          Reporter: kjslag at gmail.com
  Target Milestone: ---

Okular renders some pdfs much slower than Evince, even though both use Poppler
for the pdf backend. Since the same backend is used, I would expect the pdf
render time to be the same.

For example, the second page of this pdf
https://arxiv.org/pdf/1701.07837v2
takes over 3 seconds for Okular to render. However, Evince renders it almost
instantly.

Or when quickly scrolling through a large pdf, Evince seems to render the pages
almost instantly, while Okular renders slower than I can (quickly) scroll. Here
is an example large pdf:
https://arxiv.org/pdf/1508.02595v4

I'm using Okular 1.3.3, Evince 3.26.0, and poppler 0.61.1 on Archlinux (with an
Intel i7-3720QM @ 2.6GHz).
