WFM with FF45 on Win 7.

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?

Comment 4

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.)
