Is there any chance your application is caching a subgraph that isn't attached to the view/contexts that are destroyed so are effectively hidden by the releaseGLObjects() operation? If you re-attach such a subgraph to a new context it's handles to GL objects will all still be there but won't be valid. If you do cache subgraphs in this way then you need to call rootnode->releaseGLObjects(); on it prior to deleting the context, or call releaseGLObjectse() afterwards then osg::discardAllGLObjects(); Robert. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
