        TextureMapperSurfaceBackingStore can import texture's from a GraphicSurface.
        In such cases GraphicsSurfaceGLX creates an XPixmap to read texture content
        from a given WindowId but doesn't create any new window.However, OffScreenRootWindow
        always tries to unmap window(in it's destruction) resulting in segfault.Now,We try to check for a valid
        Window before trying to unmap the window.
