+  Linux and other X users may need to try toggling this flag if the main display 
+  window is causing them problems. For example with this unset, KDE users may 
+  find the main display window disappears if they switch windows. Ubuntu users 
+  using the Unity interface may find the main screen is corrupted if set. GNOME 
+  Shell users may find the window doesn't fill the whole screen if unset. As it 
+  appears to affect different versions and distributions differently, this 
+  setting has been added, rather than try and work it out programmatically.
