Bug#707187: iceweasel: incorrect rendering at the bottom of a page

Wed May 8 02:39:32 UTC 2013

Package: iceweasel
Version: 20.0-1
Severity: important

On 2013-05-07, with iceweasel 20.0-1 using no extensions except
Stylish 1.3.1, and the following global style:

@namespace url(http://www.w3.org/1999/xhtml);
html { font-size: medium !important }

I get rendering problems on the following URL:

http://www.lebardegandi.net/post/2013/04/25/L-IaaS-va-passer-en-paiement-à-la-consommation

near or at the end of the page. What is displayed depends on what
was displayed before hitting the [End] key. Moving the mouse may
be sufficient to make the black background appear.

I had been reading this page from time to time since 2013-04-25, but
this rendering problem didn't appear until now. The cause seems to
be new comments on the page, which needs to be large enough to make
the problem appear.

There was a recent cairo upgrade from 1.12.2-3 to 1.12.14-2, and xorg
upgrade from 7.7+2 to 7.7+3, but downgrading all the corresponding
binary packages and restarting Iceweasel doesn't make the problem
disappear. Downgrading the kernel doesn't change anything either.

By saving the page locally (as "complete") and adding

  html { font-size: medium !important }

to the styles, one no longer needs the Stylish extension.
