User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release)
Build ID: 20130910160258

Steps to reproduce:

Open the attached PDF file with the internal PDF viewer (or see the attached screenshot)


Actual results:

Previous versions of FF displayed our invoice PDFs without any problem. Starting with the most recent updated (FF 24) the text is scrambled in the whole document.


Expected results:

The PDF should be displayed without any graphical issues.
This is a new bug forked from an old issue, 921409, as requested by Brendan Dahl.

Looks OK here on GNU/Linux and w/o hardware acceleration (blocked):
 firefox-23.0.1.en-US.linux64,
 firefox-24.0.en-US.linux64,
 in Firefox 25.0 Beta,
 in 2013-10-06-03-02-01-mozilla-central-firefox-27.0a1.en-US.linux-x86_64.


Does it depend on whether hardware acceleration is enabled (Tools → Options → Advanced)?
Flags: needinfo?(andreas.toom)

Hi,

I renders OK when I turn of hardware acceleration!
Flags: needinfo?(andreas.toom)
Please check if the issue exists in the latest Nightly https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-central/

If yes (or if you want to), use mozregression http://harthur.github.io/mozregression/  to find out when the bug appeared.

I used mozregression, great tool!

This is the result:

Last good nightly: 2013-05-17
First bad nightly: 2013-05-18

OK, maybe it did appear due to the PDF.js update (bug 871530).  The bug is blocked by bug 901288 and bug 921409 (in which you posted about this one first).

Can you determine if report is a duplicate and if it is likely that it will be resolved through 901228 or 921409 ?
*I* cannot.

Development of PDF.js happens at https://github.com/mozilla/pdf.js, and it might be possible to find the regression range in that code.
Can you paste the graphics section from about:support?
