That should not be needed at all, and indicative that something somewhere
in your application or it's usage of the OSG is messing up the GL object
management.

The resizeGLObjbectBuffer() is only needed when graphics context are
created or destroyed.


As to what is going wrong your case I can't say - something *very* odd is
happening.  Are you creating your own graphics context / modifying the
viewer?
