This part has already been answered, so I will comment only the second
question:

Likely, this problem is due to the Depth-cuing and very dark monitor
setting.
(depth-cuing means the farthest the object from your eyes the darker its
appearance). The "depth-cuing" was enabled by default for the
Fermi-surface (FS) display in version Beta-1.0, but in version 1.4 this
was changed: it is disabled now.

To toggle depth-cuing (or anti-aliasing and other display settings):
mouse-click with the right button on the FS display window. The menu
will pop-up. Select: "Display->Depth-Cuing".
