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?
Priority: -- → P3
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.)
Summary: Parts of text of PDF file not displayed → Parts of text of PDF file not displayed when Firefox built with internal copy of Cairo
