                    GTK decorations
           Product: Wine
           Version: 1.9.13
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED

When selecting a Windows version higher than Windows XP to use for the
application, the client uses a GTK titlebar instead of the native one that
comes with the application.

Note that the Internet (Shop and Game Notifications) aren't working either, but
this is a seperate issue and only applies to Windows versions higher than
Windows Vista.
