Fails for me, too, on a 3.5 year old Dell XPS laptop, Windows 8.1,
with an Intel HD Graphics 4000 running driver version 10.18.10.3316. I
get your TestCase app window with nothing but an empty (white) client
region.
An app we have built against VTK 6.2-ish with the old OpenGL using
VolumeSmartMapper works fine on this very same machine.
Another data point...
