Hi Raymond,

Thanks for the logs, unfortunately the debug logs actually make it
more difficult to spot the actual errors.   The only error I spotted

Warning: detected OpenGL error 'invalid operation' at after RenderBin::draw(..)

Is this the error you are thinking of?

Could you set the OSG_NOTIFY_LEVEL back to NOTICE and the env

This hopefully will enable us to home in a bit more closely to what
might be causing the GL error.

Another useful bit of information is the last OSG version that doesn't
report the above error on our system.  It could be that the cause of
the GL error precedes the VAO work.
