If you are running the Optimizer on the scene, then the fix to osg::StateSet
which was checked into CVS on Monday may be relevant here. Without
it the Optimizer could incorrectly eliminate (otherwise identical) state
sets
with different render bins. I encountered the problem in a similar
situation
to yours, trying to display text with a higher render bin than the rest
of the
scene.
