I think a possible workaround would be to make an osg::isGLExtensionSupported call inside SceneView::init(), just before the GLObejctsVisitor traverses the scene. I suspect this might be more reliable than the previous disable of the compile of display lists inside the GLObjectsVistor.

Hi Marc,
If the bug is solely caused by calling
wglGetProcAddress("wglGetExtensionsStringARB") within the initial
display list compilation, then I believe that adding the call to
osg::isGLExtensionSupported for each context prior to SceneView::init
*should* avoid the problem by forcing the call to occur outside of
display list compilation. Have you had the chance to try this out in
your application?
I don't know if the previous workaround of disabling display list
compilation during init would guarantee that this call sequence would
not happen later (e.g. during rendering of the first frame).
Can you let us know your support ticket number, when you get one? It
turns out my company has an NVIDIA contact; I can let him know that
we're also in need of a fix for this issue.

Hi all,
Nice catch Mike. What do you guys suggest as a temporary fix until
NVidia reacts to this? I will test the suggested fix as soon as I can.
I have sent a ZIP to NVidia with the osgGLUTsimple.exe app and a 3DS
file. I do not know if it will make it to the NVidia team but I received
an Email saying they should get back within 24 hours. I will try to send
the new information provided by Mike to update the support ticket.
Regards,
