When you say "weird" what do you mean? If you have polygons that are
positioned/aligned very closely to one another you might be seeing
z-fighting (http://www.zeuscmd.com/tutorials/opengl/15-PolygonOffset.php).
In that case you can tell OpenSceneGraph to use polygon offset on one of
the models.
osg::ref_ptr<osg::PolygonOffset> polyOffset = new osg::PolygonOffset;
polyOffset->setFactor(1.0f);
polyOffset->setUnits(1.0f);
ss = someNode->getOrCreateStateSet();
ss->setAttributeAndModes(polyOffset);
