I've been running nightly with this enabled for quite a while on Intel

Note that OMTC is required for e10s.


If you mean OMTC by "this" then you're right - it works fine on nightly
because nightly is built with in-tree cairo. Fedora it built with system
cairo which causes crashes with OMTC enabled. First build which supports
in-tree cairo & Gtk3 is FF41.

Why? What's the difference between the in-tree and the system cairo?
Ist it newer? Older? Patched? Or just built with a different
configuration?

in-tree cairo is a cairo library intergated in firefox tree, patched for mozilla needs and used for internal rendering. system cairo is a cairo library shipped in Fedora and used by gtk3 to draw.
