Hi CG
When your remove a shader, "void Program::dirtyProgram()" is called to request a relink in the next frame. Program is relinked in the next frame in "void Program::apply( osg::State& state ) const" method. Follow your code in a debugger to see if all is properly done. Are you sure your shader is well removed from your program ?
