Okular renders pdf fonts incorrectly

[Mikael Gerdin]

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.

Okular uses poppler for PDF rendering.

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.

Might not be an Ubuntu-specific bug actually: https://bugs.kde.org/buglist.cgi?content=font*&field-1-0-0=product&field-1-1-0=content&product=okular&query_format=specific&remaction=&type-1-0-0=anyexact&type-1-1-0=matches&value-1-0-0=okular&value-1-1-0=font*&order=bugs.bug_id desc&query_based_on=

Alright, my problem is subpixel rendering and isn't related to Mikael Gerdin bug, my apologies..
