What steps should I take to try to reproduce this? You said you can't find any logic in the behavior - does that mean it appears completely randomly? If you load a song, then close it, and reload it again, are you saying that it could select a different layer to show when doing that with no other interactions? I've certainly done a lot of testing with multiple layers and I've never seen a hidden layer suddenly shown for no explanation. Are you currently using the touch action to cycle through layers?

Thanks,
Mike
