Hi JP,
Yes, that is exactly it. The temporary fix below did work. Did we find
yet what is the exact code change that triggered this between OSG 1.0
and 1.1? The link with display lists and drawing contexts sounds logical
with the symptoms that were reported. My application runs in stereo so I
assume I setup two separate contexts. I run on an NVIDIA as you already
guessed and am using osgUtil::SceneView too. My NVIDIA driver version
is: 78.01.
If the problem is out of the OSG community control, maybe an interim
solution could be to track down the OSG code that caused this and revert
back, that would allow to remove this annoyance from the next OSG
releases until NVIDIA can help on this. This is assuming that the OSG
changes triggering this bug are not absolutely necessary and could be
achieved using a different coding method.
Any news on this issue regarding a permanent solution? What is the
position of Robert and others on this?
Thanks JP for the pointer. It helps a lot!
Regards,

Hi Marc,
I'm taking a guess here, but it sounds like the same problem some people
ran into with using SceneView (post OSG 1.0), display lists and NVidia
cards on Windows.
I'm not sure if VRJuggler uses SceneView, but search for the threads by
"Gian Lorenzetto" on model loading.
The workaround suggested by Robert was this (supposing you are using
SceneView):
------8<------------
sceneview = new osgUtil::SceneView;
sceneview->setDefaults();
sceneview->setInitVisitor(new
osgUtil::GLObjectsVisitor(osgUtil::GLObjectsVisitor::COMPILE_STATE_ATTRIBUTES));
sceneview_->setSceneData(...
------8<------------
regards
jp
