ofFbo issues when samples > 0

Hi, I am finding weird issues when drawing one FBO inside another one.

	int numSamples = 8;
	fbo1.allocate(300,300, GL_RGBA, numSamples);
	fbo2.allocate(300,300, GL_RGBA, numSamples);

	fbo1.begin();
	ofClear(0,0,55,255);
	ofDrawCircle(mouseX, mouseY, 33);
	fbo1.end();

	fbo2.begin();
	fbo1.draw(0,0);
	fbo2.end();

This should draw nothing to screen, but if numSamples is > 0, it does. In my setup (today’s github master, OS X 10.10.4) it draws fbo1 on the bottom left of my screen, flipped vertically.

can you open an issue in github?

yep, just did. I’ve had other issues with multisample fbo’s in the past, but the symptoms seem to keep changing.
