I'm aware, but I was talking about the lobby area, before you start a video.
When I would load up Skybox, both controllers would be invisible. There was also no white line coming out of where the controllers should have been. The only thing I saw was the white dot on the menu before me to select something with, but it didn't move when I moved either controller. It would have been impossible for me to even start a video.
I tried to press the Oculus button to make a screenshot, but as soon as I did that, I saw my controllers again, and when I returned to Skybox they were visible there as well.
It doesn't happen very often though, so it's not a deal breaker at all. It just seems like a weird quirk the app sometimes has.
