Cairo update?

Comment 2

Seems like the most likely cause. CoreGraphics Azure should fix this but is currently only enabled with OMTC.

Does this still reproduce in the current Firefox Nightly?

With HWA forced off and `mozregression --find-fix --bad 2011-05-26 --good 2016-08-15`:

It seems like something in that range caused this to not be reproducible by simply disabling Fx HWA on my Macbook Pro but I'm not sure if that means it's fixed for everyone or it depends on the OS (version) or hardware.

about:support has the identical graphics info for both builds:

I suspect this may have to do with enabling Azure content via bug 907926.
