This is very nearly permafail: https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&fromchange=8a2f028e6943d68259be6e3082f07acd67c3b085&bugfiler&noautoclassify&filter-searchStr=5de9026cafc77392c801413879dd31d4676cdef1&selectedJob=76934766&group_state=expanded

Comment 2

[Olli Pettay [:smaug][[e-mail]]]

yup, I started to look at this earlier today. 
(this was permafail locally already before my changes.)

I'll continue tomorrow.

Looks like a single pixel of anti-aliasing difference to me.
Adding fuzzy-if(Android,4,1) to the manifest file should fix it.

Comment 4

[Olli Pettay [:smaug][[e-mail]]]

oh, I'll try that.
(the local difference is way more)
