Research direction
Reproduce the issue in main using ofSetCurrentRenderer(ofGLProgrammableRenderer::TYPE) and an ofxCvGrayscaleImage, then compare it with that line commented out. Trace the grayscale image draw path and OpenGL 3.0 renderer behavior; done means the image renders visibly rather than black with the programmable renderer enabled.
