I am also experiencing this on my Lenovo X200. I have tried with
external 1920x1600 and 1920x1080 monitors. I get the black bar across
part of the external monitor thing.

It works fine with compiz and without unity. It works fine with unity 2d
(without compiz). But the combination of compiz and Unity is bad.

I've tried running:
* compiz --replace
and
* unity --restart

And sometimes the desktop is fixed, but not always.

If I select different resolutions for the monitors, the band sometimes
goes away or appears in a different location.

Weirdly, when I have the black bars, the mouse cursor can go over the
black bars and you see it. Anything else can go into the black region
and it's like, it goes there, but it is behind a black mask.

When I use the super-S "expo" feature I can see all the desktops and
they do not have black bars on them (though the black bar remains on the
external monitor.

Also, if I start from login with the external monitor, I do not have the
problem. It is only when I try to plug the running system in that it
occurs. Starting from login and unplugging the external monitor creates
a similar problem. Only this time it is a thin blue band across the
middle of the laptop screen and all of the windows are arranged below
the band. However, I can drag the windows above the band or half way
with the band covering the middle of the window. The point is, that it
seems to recognize that the two sides of the band are two different
regions. Almost as if it is treating the two sides of the blue band as
separate monitors.
