I see this problem with 1.9.2 builds, but it renders correctly on trunk.

Comment 2

[Frédéric Wang (:fredw)]

The bug with 1.9.2 builds is probably due to an incorrect installation of STIX fonts:
https://developer.mozilla.org/en/Mozilla_MathML_Project/Fonts#STIX_Fonts

Note that Mozilla 1.9.2 still needs some fonts from STIX Beta and that's why it was suggested to take bug 569195 and related to the 1.9.2 branch.

This bug is fixed on trunk even without STIX fonts installed, by the workaround of bug 414277.

Ah, I definitely don't see STIX installed on this box.

I installed STIX fonts. Problem went away. Thank you!
