X11WindowSystem : Fixing wrong composition.

- If a running application will be destroyed or the window
  will be unmapped, there was an issue that the composition will
  display garbage at top of any surfaces.

- Due to the fact that enableRendering and disableRendering is introduced
  that issue is fixed.
