--- Comment #5 from Jerome <ce0c5679c447a438 at mailinator.com> ---
Just updating the developers, that the poppler developers pointed out an issue 
in freetype's use of a new font hinting engine contributed by Adobe 
which has a  feature called "stem darkening". It appears it's on by default
and that the default values interact badly with how poppler does rendering (In
a way
I do no understand).

The freetype developers have confirmed the issue.

There is a runtime option for freetype that allows you to turn off stem
darkening,
and by using it in poppler I was able to eliminate (practically) the problem.

I'd like to suggest that the okular developers track this, and would be glad to
see 
it handled in a coming release by whatever form the solution takes.
