Public bug reported:

Binary package hint: xorg

I've been using dual head with open source ati randeon driver (or with
fglrx) for some time and maximized windows only fill one monitor.

I've now added a 3rd monitor using displaylink USB graphics card.

So I have 2 X screens: one is my ati radeon with 2 monitors, and one is
the display link.

Windows on the ati which are maximized now fill two monitors instead of
just one.

xrandr (when run on the 2 screens) reports the two screens properly.
xrandr (when run on the 1 screen) reports that properly too.

So I don't know why the maximizing should have changed.

I'm not using xinerama although when I was it had the same behaviour.
