Transition between menu bar and windows broken in maximized state

[Hendrik Schrieber]

When having a window in maximized state there is an ugly whiteish line between menu bar and actual window (see attached screenshots). If the window is restored and maximized again the line disappears until the cursor is moved onto the global menu (menu bar). This happens in a VM. Haven't tried on a "real" system yet.
