After creating a texture widget, it cannot be destroyed.
The MFD on the left in the rover should destroy the widget after 10 seconds, but fails to do so.
This is also the case for the central MFD. Click the 'Hi Res' button and a texture widget is created. Clicking the new texture widget should destroy it, but does not. Using 'Destroy all widgets' instead of naming the widget to be destroyed also failed to destroy the texture widget.
