It should be three things: transparent, solid color and checkers pattern. That's what I have in my tlRender branch.

Note that I found two things with your current implementation:

ui::checkers() with p.render->drawColorMesh() does not work on macOS (it seems macOS does not support colored VBOs?)
With your Qt and GLFW sample code, your compositing doubles the alpha channel. In mrv2, I separated the code to a separate offscreen buffer to avoid that.
