Update:
I tried this with 32bit Ubuntu and it has the same issue with 3D option, 
and also same on vbox-4.1.10.
I exported 32bit Ubuntu as an appliance and imported it into Mac OS 
32bit, and Ubuntu guest doesn't even show panels there at all with 3D 
option.
I filed the PR upstream: https://www.virtualbox.org/ticket/10392
