Bug#623097: iceweasel: high CPU usage by Xorg on page loading when "Tabs on Top" are off

Package: iceweasel
Version: 4.0-3
Severity: normal

CPU usage by Xorg process is very high while page is loading (constantly about
50-80%) if option "Tabs on Top" is off (by default it is on). You can change
this option in context menu of any panel. Disabling tab loading animation by
editing userChrome.css solves problem completely. It is reproducable on clean
profile of iceweasel. I've downloaded Firefox directly from Mozilla and bug is
not reproducable on it.

I'm using GNOME Desktop Environment (only part of it actually), Nvidia
proprietary drivers from debian package (version 270.30), and I have no
compositing enabled.
