Steps to reproduce:

Created a CSS triangle with borders - http://jsbin.com/opusan/1/edit


Actual results:

Border was aliased, unless border style for transparent sides were 'dotted'


Expected results:

Anti-aliased in both cases.

I believe the 'dotted' thing works around those bugs too

This could very well be a graphics bug, but I'm going to throw it into the CSS bucket for now so they can weigh in first.

On Linux, I see the same regression window as bug 965966 comment 5, which was well after this bug was filed; the behavior prior to the regression matches the summary of the two "Possibly related" bugs in comment 0.

Was Azure enabled on Mac when this was reported?
