Hi Robert, I tried adding the setShaderHint() line but things get a bit worse - alpha issue still there and not text at all, see attached screenshot.
I get display errors also in my other HUD contents where I actually use gl_ builtins so your guess might be right, but unfortunately adding the ShaderHint does not fix it.
