So.... you disable depth test? If you have depth test on then you will be using the depth buffer even with 2D projections.. as 2D projections are really no different rather 3D projections in OpenGL, everything in reality is 3D, everything has depth even it's flat and depth value of 0, and if depth test is on then each fragment will be tested against the depth buffer. > For a simple OpenGL program I just draw components in sequence.
