The bottom left corner of the text box is different. It's not at all clear why yet. Further, PIX is being very stubborn as of late.

PIX appears to be partially made stubborn for me by the GPU memcpy things (what we're doing seems to be valid though :s but PIX seems to hate it). Try commenting out that optimization piece (just use normal rendering for it), it may improve your results.
So it looks like this is actually layout bug. We seem to be drawing an underline under at the bottom of the text box. If you change the text-decoration to line-through this becomes obvious. We're the only browser that does this and it seems wrong. It shows up as far back as 3.6
Why does this show up only on Windows 7?
uh.. on Direct2D?
We suspect it's because of something more, or less accurate in D2D rasterization. But the fundamental bug is definitely there elsewhere.
I've filed a bug against layout for the text-decoration problem (bug 586748)
