Bug#618468: iceweasel: text not completely redrawn when scrolling to the right

Package: iceweasel
Version: 3.5.17-1
Severity: minor

When scrolling to the right, text may not completely be redrawn.
This problem is 100% reproducible on some page (it is private, so
that I can't provide it) when scrolling slowly.

I've attached 2 snapshots: the first one showing incomplete redraw,
and the second one showing correct text. The redraw is completed
juste after taking the snapshot (with "import -window root ..."
from FVWM) and when the window loses the focus.

Scrolling in the other directions (left, up, down) doesn't yield
any text corruption.

As this could be related with the driver, my /etc/X11/xorg.conf file:

Section "Device"
        Identifier      "Device0"
        Driver          "nouveau"
        # See nouveau(4) man page.
        # Workaround for Debian bug 614938 / FreeDesktop bug 33977.
        Option          "WrappedFB" "true"
EndSection
