730123 - Apparent regression showing up in canvas-based font systems

Status: RESOLVED DUPLICATE of bug 729850

(Core :: Graphics: Canvas2D, defect)

Description

Attachment: about:support

I've been seeing a couple of regressions in font handling:

 - the online app lucidcharts looks like hell (see menus and text in the screenshot at http://imgur.com/oyAIY)
 - the Cufon.js font conversion tool (that takes OTF and TTF files and creates SVG/Canvas bases renderings) doesn't look good at all on nightlies: compare the heading on http://cufon.shoqolate.com/generate/ on Nightly vs. Firefox.
 - (as another example of the latter, on my own blog http://blog.ascher.ca/ the H1 and H2 elements look quite off in Nightly.

I'll attach my about:support data in case it helps.  I've had at least one confirmation from someone else using nightlies on my blog.

Note font menu and very weird font display. Feels like a math path bug.

sstangl saw the same thing on OSX, and it's not seen on linux or windows.

David, are you looking for the regression range, or does someone else need to?

Might be bug 729850.

I'm not, sorry.  I've noticed it in the last few days, but I don't often look at my blog, so it's not a strong clue.

Removing qawanted since this was duped to a fixed bug. Please re-add if there is something more that is needed.
