No both in the 'maximized' state and on restored the window is exactly
the same (though in a different position relative to the rest of the
screen). The one difference is that the emacs frame which was
originally showing two windows now only shows one window. I'm
including a screenshot of the maximised state. Other applications
maximise as expected - as does emacs when the desktop isn't loaded.
(I commented in a previous message that maximise isn't working
properly when the frame is in this state).

Is the maximise state happening but the border is only giving a
partial window and the other buffer is there but the frame cuts off
visibility?

Exactly the same behaviour as in case (1)

I exited the bad state emacs but with only one window shown in the
frame and then restarted emacs and the frame was displayed correctly!
I then displayed another buffer in a second window in that frame and
exited again. On a restart the problem was back.
The problem only seems to occur when the frame is trying to show 2
buffers?
