I am not sure this is logged in the right place, it might belong against
poppler. I can't see any duplicate bugs, but apologies if so, I don't know
what I am doing.
So, many PDFs render fine for me, but some produce terribly blocky text. I
don't have any examples that I can redistribute, but any journal article
downloaded from www.jstor.org seems to exhibit the problem.
I have have done some research to try and figure out what is going on. The
following bug reports against ubuntu and arch-linux seem to repeat what I
see, and suggest it is to do with a conflict between application
anti-aliasing and freetype autohinting when pdfs include embedded fonts, and
that some packages (poppler derived) don't use fontconfig and so a simple
dpkg-reconfigure fontconfig-config is not enough. See:
https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/48146
http://groups.google.cl/group/arch-linux/browse_thread/thread/5402873a6e65c151
A patch is suggested in the ubuntu thread (against poppler) that disables
freetype autohinting at compile time. I have not tried applying and
recompiling for a range of reasons not worth exploring. It is as follows:

Does this mean anything to anyone?
Thanks.
