741273 - Firefox renders font poorly in certain pdf files

Status: RESOLVED DUPLICATE of bug 738648

(Firefox :: PDF Viewer, defect)

Description

[Alan Bortu]

Attachment: Firefox 14, built in pdf reader

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20120401 Firefox/14.0a1
Build ID: 20120401192420

Steps to reproduce:

On the latest nightly build that I had downloaded from https://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-win32/1333333460/ I tried to read a pdf file from my universities website.


Actual results:

When I opened the pdf file in a new tab, I found the font rendering was very ugly (see uploaded picture). This does not happen in chrome of with the SumatraPDF plugin. The pdf is located here: http://www.cs.utoronto.ca/~tff/165/lectures/ch6.pdf


Expected results:

It should have rendered the font normally without all the jagged edges.

I have attached a comparison between PDF Viewer 0.2.414 and Evince on Ubuntu 10.10 64 bits and indeed fonts are poorly rendered on PDF Viewer

The problem seems to be fixed in this pdf but I have found another one where the text is not displayed properly. You need a university account to access the file so I have just uploaded it instead.
