I think this is expected behaviour.

 From <http://en.wikipedia.org/wiki/GLX>:

    GLX consists of three parts:
    - An API that provides OpenGL functions to an X Window System
    - An extension of the X protocol, which allows the client (the
    OpenGL application) to send 3D rendering commands to the X server
    (the software responsible for the display). The client and server
    software may run on different computers.
    - An extension of the X server that receives the rendering commands
    from the client and either passes them on to a hardware-accelerated
    3D graphics card or renders them in software, usually using the
    Mesa library (which is much slower).

Assuming that 3rd component is running I think the video hardware on  
the FE will be updating the menus, rendering then unavailable to the  
VNC server.
