This was Robert's response to a similar situation:

--->
Its likely that some OpenGL state you are setting isn't supported on
your hardware.  The big question is what OpenGL features are causing
this problem.  You could enable finer grained checking for OpenGL errros
via osg::State::setCheckForGLErrors(osg:State::ONCE_PER_ATTRIBUTE);
Or enable by tweaking the State constructor in src/osg/State.cpp.
You'll see a block:

#if 1
    _checkGLErrors = ONCE_PER_FRAME;
#else
    _checkGLErrors = ONCE_PER_ATTRIBUTE; #endif

Just change the #if 1 to #if 0.

This might give you a bit more info.

Robert.
