on my fresh install of Linux Mint 13 XFCE I encountered a strange behaviour of the window managing. When I go to fullscreen, I have a margin of maybe 10px around the maximized window. This margin is on the top, left and right side of the maximized window. I can see my desktop fringe behind that window, or other windows that are still open.
When I manually drag a window to all the borders, I get a real fullscreen.
I attached a screenshot to demonstrate. Is this a bug or a feature? I checked several menus regarding window and desktop behaviour, but couldn't find anything. Also, websearching didn't bring up anything worthwhile.
Thanks in advance,
