Hi,
see this discussion:
http://thread.gmane.org/gmane.comp.graphics.openscenegraph.cvs/4260
I can also suggest you use/look at the code of the osgEarth overlay
classes, I think it handles the view-dependent overlays a bit better.

I was looking at the example osganimate and I attempted to use the
--ortho option which sets the overlay technique to
osgSim::OverlayNode::VIEW_DEPENDENT_WITH_ORTHOGRAPHIC_OVERLAY. However,
nothing is overlaid when this method is selected. My assumption is that
this method should increase the resolution of the overlaid image as the
viewer is zooming into the object receiving the overlay.
Someone mentioned that J.P.Delport had a patch to fix this method, but I
couldn't find any information on it. I also looked in the trunk and
didn't see any updates related to this change.
