I can re-test VERDE when I get home.
I haven't investigated why the hw hangs, because it only happens if shader
compilation fails and so none of the sample_shading shader stuff makes it to
the driver. I think the likely cause is that Unigine attempted to do rendering
with a shader that hasn't actually been compiled and things went wrong after
that.</pre>
