Description Eugenio 2014-06-24 12:39:06 UTC

With some pdf (exported from libreoffice impress) okular uses 100% of one cpu. After a long time it ends and loads correctly the pdf.
Other pdf viewer (e.g. evince) work as expected (loads in 1-2 sec and without using a lot of cpu).
I found that the problem seems to be this particular background.

Reproducible: Always

poppler 0.26, Okular from git/master.

This is a problem in poppler the pdf rendering library we use. Please go to https://bugs.freedesktop.org and report a bug against poppler product in the splash renderer component.
