Steps to reproduce:

Some parts of PDF files from http://www.japaneseaudiolessons.com/japanese-grammar-quiz/ ("Answer to Question # ...") are not displayed.

I use Firefox 45.0. Problem was present also in older versions.

I attach screenshot showing incorrect display of http://www.japaneseaudiolessons.com/wp-content/uploads/Answer-to-Question-11.pdf in Firefox.

Apparently reproducibility of this bug (on GNU/Linux) depends on version of Cairo.
Bug is present when using bundled version of Cairo.
Bug is absent when using system version of Cairo (currently 1.14.6).
I am unable to reproduce on ubuntu with the default cairo version. What distro are you on?

Gentoo.
Problem still present in Firefox 45.0.1.

(Unfortunately when Firefox is built with using of system Cairo, then segmentation fault occurs when opening some sites.)
