Is there an option to hide/disable the "volume" display in edit mode? It seems that when the object is rotated in Edit Mode the "volume" representation will sometimes change, appear and disappear and various angles and distances.  I figure there is an option somewhere that I haven't discovered but, in the meantime, does anyone know if it's possible to turn the "volume" display off?  It's not bad but it can be distracting.

thanks
I think your issue is related to the display camera's clipping distance. Clipping distance is basically the distance the camera can view.

You can change the settings around in the properties panel (N):
