Hi Robert, The problem is that the applications we're developing are predominantly desktop applications that don't use stereo. The addition of stereo is used predominantly for demos since it carries a certain wow factor. Prior to moving to QT we were simply using an osgViewer framework and that did work perfectly in all stereo formats. However, this meant using opengl/osg rendered interfaces and we were struggling to find a GUI library that could support the level of interaction and quality of rendering that we required within an opengl context.
My decision to move to QT for this was all going well until I was blind sided by this horizontal split requirement. Kim.
