      That might not be so easy as the bug currently occurs in a huge
      software project. Creating a small example might not be so easy as
      I don't really know vtk and opengl. We're just trying to fix bugs
      in older code.<br>
      <br>
      But maybe you have some ideas where we could look for. Maybe
      something (buffers, flags, ...) was not cleared correctly?<br>
      I am currently trying to find the problem using glIntercept. Or do
      you have any other tipps for debugging opengl?<br>
      <br>
      Again, thank you.<br>

                            <br>
                            it took some time to test everything you
                            suggested as I didn't have much time for it.
                            It turns out that stereo rendering is
                            disabled using the methods mentioned here,
                            but I ran into some other strange,
                            stereo-related problems in rendering. When I
                            now render any 2D objects with stereo
                            enabled in the render window but disabled in
                            the camera, the first object has is rendered
                            in stereo. Once I add a 3D poly data object
                            to the renderer, everything is fine and the
                            2D object is rendered non-stereo. When I
                            then remove the 3D object, the problem
                            appears again.<br>
