Thanks for the reports. Do you have any idea when this started failing (i.e. last know good version)?

Probably started when we enabled subpixel on Mac.

(In reply to comment #4) > Probably started when we enabled subpixel on Mac. You are probably right. One would think that we'd have noticed it being broken in chrome/mac though.

Maybe some platform code differs.
