Screenshot results of the culling test
If gl.glEnable(GL.GL_CULL_FACE) is set, graph text rendering doesn't work with region MSAA or VBAA. It works ok with full scene MSAA or no anti-aliasing.
If it can't be made to work with culling, the quick solution would be to simply disable GL_CULL_FACE before rendering, and enable it afterwards, maybe via a new hintMask or custom enable/disable callbacks for renderer.
