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)?

Hi, I renders OK when I turn of hardware acceleration!

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 Pushlog: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ea767da526ff&tochan ge=6e2789a70f6b

https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ea767da526ff&tochange=6e2789a70f6b 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?

Has there been any progress on this?
