Bug#597717: iceweasel: incorrect redraw when scrolling a "View Page Source" window

Package: iceweasel
Version: 3.5.13-1
Severity: minor

When choosing "View Page Source" and scrolling downwards with the
mouse wheel, the redraw is sometimes incorrect: some lines (in the
sense lines of pixels) contain incorrect data (probably because
some parts of the window have not been redrawn, but I'm not sure).

This is not very hard to reproduce here, but it can take several
dozens of seconds. I don't know the conditions, but it seems that
the lower part of the window should be off-screen. Also this should
be tried just after a page reload (it seems that if the source was
already displayed correctly, the problem is more difficult to
reproduce).

Once I do any operation involving the window manager (fvwm), the
window is redisplayed correctly. That's why I can't provide a
screenshot.
