If so, I'm planning to make my GUI objects to be drawn with ofFbo only and only re-write each GUI into the buffer whenever there's an update in GUI's property (i.e size, color..).
For example, if I create a button GUI, it will be drawn by ofFbo and only if I press the button so the color should be changed, it will be drawn with common object(ofCircle, ofRect) until re-writing the new one into the buffer gets done.
Could this be a good idea for getting the extra efficiency?
