mono gtk maximize but still space on top

Question

Hy all,

I'm playing around with monodevelop and am using gtk for the window. Curently i'm using Windows 7 x64.

The problem that i'm having is that when i'm maximizing the window ( by hand or by program, that doesn't matter ) there's still some space at the top of the page left. And it doesn't connect well at the bottom of the screen. So it looks like the whole program is maximized, and then put down a couple of pixels.

Here's an screenshot of the maximized window:

As you can see in the second printscreen, it is posible to get the program at that top:

So my question is very simple... How can i get the window maximized in a good way that is normal...

I can successfully reproduce this behaviour on my Windows 8 box.

It seems to come from the WindowPosition setted to CenterAlways. Yet the documentation warns us on the usage :

Note that using GTK_WIN_POS_CENTER_ALWAYS is almost always a bad idea. It won't necessarily work well with all window managers or on all windowing systems.

Setting the WindowPosition to None (0) fixed the issue for me.
