Public bug reported:

I have 4 monitors in a single X display using NVidia Base Mosaic. Using
Ubuntu GNOME

I have two landscape monitors stacked with a portrait on either side.

If the portrait monitors are configured such that the BOTTOM of their
screens align with the BOTTOM landscape monitor, both portraits and the
bottom landscape monitor will not display anything below the lower 1/2
of the screen. I can move the pointer to the lower portion of the
screen, and see the pointer there, but if I try and drag a window it
acts as if there's an artificial bottom. It seems that the size of the
non-displayable area is the same as the distance between the top of the
portrait screens and the top of the landscape screens.

(I attached a screenshot of the displays configuration. The problem is
when 3 and 4 are bottom aligned)

If the portrait monitors are configured such that the TOP of their
screens align with the TOP landscape monitor, everything works as
expected.

I do not believe this is an explicit X server issue because if I take my
Gnome monitors.xml and have lightdm use that, everything works as
expected. I believe it is related to the Gnome display manager.  It is
as if something that is deciding what the visible display area is has
some bad math with this layout.

This was all functioning properly under 14.04.
