window manager: metacity with compositing enabled

notice: when talking about Steam windows I mean every window that Steam opens.
It can be the main window, but also the "Connecting Steam account", properties,
Friends, etc.

Screen under Steam windows is not refreshing, but only the part that is below
and to the right of top left corner of Steam window.

On the screenshot you can see the Firefox window with scrolled page and Avant
Window Navigator with autohiding.
