On RaspPi
- In 1920x1280 the emulator cachtes the whole screen. In the left and 
right black border (left & right to the oberon screen, which is in the 
center) you can see the window manager mouse pointer.
- The Oberon screen is not part of normal WM Window. May be it is, but 
it looks if its not.

Anyway, the behaviour is different to that of other linux systems, f.e. 
debian / ubuntu on x86. Here is
Oberon Screen is per default part of a window which i can grab and move 
around. I see no reason, why
FXDE on RaspPi should behave other as Gnome/Unity on my x86.

Btw, it is also possible to start the emulator without a x-server running.

You can try it on your RaspPi. If you have a solution here, it would be 
nice.
