splash slower than cairo at rendering a pdf
Submitted by Kevin

Okular renders some pdfs much slower than Evince, even though both use Poppler for the pdf backend. Apparently, this is because Evince uses the cairo backend of Poppler, while Okular must use splash.
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).
