shaped winForm app by backcolor

I want to have a shaped WinForm window or called irregular Window work in
openSUSE.
I know there are two way to get a shaped window. One is using Region when
form_load, the other one is using backcolor to transparent part of Form.
I verified both of them in Windows, they all work.
But copy the same code to openSUSE, build with mono 2.0( MonoDevelop 1.9.1)
Both of them didn't work. There always have a window frame and title bar. And
also the form is not shaped when redraw.(still a rect and can't redraw when
move).

The BackColor sample code is attached as zip file.

The Region way code is followed.

Expect result:
works like Windows, have a irregular window shape.

Thanks,
William L.
