My 2 Roku 3's are on 7.1.4062-04. I do not see this - dev channel, dev channel screensaver
Because it seems mysterious
, i was wondering if you are doing any component mixing ( built-in components in a roScreen app for instance)? There is a behavior that I ran into, and have seen descriptions of something that sounds very similar with SceneGraph channels ( which I know nothing about). The behavior is this - You need to run a built-in component in a roScreen based channel. The component does it's thing and then you hit back to go somewhere else. The component exits as it should, but the "back" command somehow stays alive and proceeds to exit the next screen it comes to. Probably not related to your issue, but like i said, the mysterious part sounded familiar and i don't think this was ever addressed in the firmware.
