That one I can't explain then. The song overlay doesn't impact touch detection in any way. If that just randomly happens while you are using the app, that seems much more like an OS/firmware issue. If you can find a way to reliably cause the problem to happen, I will certainly look into and get it fixed if possible. Otherwise I'll have no idea what to look at. If it happens while transitioning between the annotations editor and the main view, then that might explain something. Your pedal actions under Settings->Touch & Pedal Settings->Pedal Actions aren't set to "Annotate Song" are they? What about touch actions?

Thanks,
Mike
