1 pixel is good.

With this (even removing “--safe-mode”), I cannot reproduce the problem.
It seems to be linked to the following line in prefs.js:

user_pref("font.mathfont-family", "CMR10, CMSY10, CMEX10, CMMI10, Symbol");

Copying prefs.js to the clean profile and adding (resp. removing) this
line triggers (resp. sloves) the bug.  However, on my main profile, if
I remove this line and start iceweasel, it is automatically added
again to prefs.js!

I added a screenshot to show how it looks on my machine.
