Comment 147 for bug 32561

I looked at firefox-3.0 also. The results are not bad, but not perfect either:

1) The original e-mail renders quickly and correctly, regardless of MOZ_DISABLE_PANGO (it's unclear if the switch has any effect at all now)
2) The sanitized e-mail that I attached "renders" fast. However, it produces a gigantic area of "no refresh" on the screen. As in, there's a part of the message that just keeps whatever was on that part of the screen before Firefox. And then, when you scroll, that part gets smeared around.
