Build ID: 20150806001005

Steps to reproduce:

1. go to Seibu Railway map.[1] 

Actual results:

Japanese letter(Kanji, Hiragana, Katagana, etc.) is shown doubled. I attached what happened when I read Seibu Railway Map.(problem pdf.png)

When I change size of page(like 100%, 170%, etc.), it is shown normally but instantly it changed and shown doubled. 

Expected results:

It should shown not doubled. When I read this pdf file with TWINUI(Windows 8 pdf reader) I can see normally.
Component: Untriaged → PDF Viewer
I tested this with firefox 39.0.3 and Firefox Developer Version 41.0a2(2015-8-10) but both has problem.
Version: 39 Branch → 40 Branch
I also tested this with Firefox 40 now but it has same problem.
It appears to be a layer issue which we don't support. (Preview on OSX also does not support this).
