HI Peterakos, Using removeAttribute(osg::StateAttribute::PROGRAM) should work.
To test whether it's working try writing the scene graph out to a .osg or .osgt file by doing a osgDB::writeNodeFile(*mySceneGraph,"before.osgt"); prior to doing the remove then once again with "after.osgt" once the remove is done. You should in theory see the removal of the program. If you don't then we have a bug in osg::StateSet, if you do then we possibly have some errant behaviour elsewhere in the OSG or you scene graph usage that is causing the state to not be affected in the way you expect it to be.
