rendering problem with iceweasel in sid

[Ólafur Jens Sigurðsson <ojsbug@gmail.com>]

Hi, I have a strange rendering problem in Iceweasel 3.0.4-1, when I
look at a page in the Icelandic wikipedia that contains some math
functions then there is a half box around the equation (the left and
top side of the box show, see for example
http://is.wikipedia.org/wiki/Logri) and when I look at some tables
like in
http://is.wikipedia.org/wiki/Listi_yfir_lönd_og_útliggjandi_yfirráðasvæði_eftir_stærð;
then there is a seperator between lines sometimes missing, like
between lines 25 and 26, 37 and 38, 49 and 50 and more.

Anyone else see this or have any idea of what could be wrong?

Cheers

Oli
