Bug #: 31250
           Summary: Virtual desktop windows getting decorated on
                    resolution change
           Product: Wine
           Version: 1.5.9
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

1. Launch a full screen game with resolution smaller than virtual desktop
resolution
2. Virtual desktop window resizes, gets window decorations
3. Close game
4. Virtual desktop resizes back to original size, but remains decorated

I have the "Allow desktop manager to decorate the windows" box unchecked, so I
wasn't expecting the virtual desktop to be decorated. It only becomes decorated
for me on resolution changes, but remains decorated until I restart wine, even
if resolution changes back to the full screen size.

Tested with Sim City 4 and Ys: The Oath in Felghana
