Hi Thanos, I haven't tried it myself yet, but you could try creating the split screen stereo up in osgViewer as two slave cameras, rather than let the lower level SceneView implement the stereo. Doing the work in osgViewer will allow the viewer to know about the viewports and hopefully do the appropriate reprojection.
