I can't see the image posted earlier but I think I get what he wants to do...
He wants a layout object for a "pause screen" of sorts that shows the minimap for the game window. Am I correct?
If so, here's how I recommend you do it:
Put the pause layout object on the second layer from the top. Put the minimap on the top layer. Always hide the minimap, until your pause layout is visible.
I just tested it and it works fine. If that's not what you were intending then, uh... good luck
