Hi Ufuk, I really can't guess what might be wrong because I know absolutely nothing about your application, I simply don't have magically powers to divine this stuff.
What I do know is that the vertex buffer objects support does usually work, others do not report problems with it, so there likely something quite specific about your setup that is introducing this problem. Try using standard examples based on osgViewer as a sanity test then work back to an test problem that more closely resembles how you use the OSG. Robert.
