Bug Description

Binary package hint: kdegraphics

When opening a pdf presentation created by ms powerpoint in okular some of the text is rendered incorrectly

If I use pdftoppm from poppler-utils to render the page to a PPM image the text looks like it's rendered correctly.

Test case: http://www.ict.kth.se/courses/ID2204/notes/ID2204-L06.pdf
page 2, the text "improved constraint propagation"

It might be related to #131523, but evince, which is also using libpoppler, renders the text correctly.

Hi,

I'm having a similar problem with most of my PDF documents. Font rendering is different within Evince and within Okular, and in Okular not exactly eye-friendly.

Example (screenshots attached below): http://www-fourier.ujf-grenoble.fr/enseignement/IMG/pdf/polygeo-2.pdf
