I don't see any strong differences between FF40 and 42 on Win 7.

Could you attach a screenshot with both renderings?

We are 2 days away from entering Beta44 RC mode. This bug is not a recent regression and not a critical release blocker. wontfixing for Fx44.

Fairly recent regression (from 42), tracking for 45+.

Marcus, can you take this one? I'm trying to find assignees for all the tracked bugs (mostly regressions and crashes) in nightly right now.

I can, but this doesn't look very serious to me, so it might have to wait a little.

Wontfix for 46, and dropping tracking for this as it's a fairly minor regression and it's been wontfixed repeatedly. It would still be nice to get a fix in though. Would it make a good first bug/mentored bug?

This came up for QE today so I'm making it clear this is still an open issue in nightly. 
I don't want this to pop back up in triage since it's a longstanding and pretty minor regression.

Marking fix-optional to indicate more clearly that a fix would be nice but we don't need to keep triaging it for current releases.
status-firefox47: --- → wontfix
status-firefox48: --- → wontfix
status-firefox49: affected → fix-optional
