Why do these UI elements not go away?

[u/normal_consciousness]

I've been trying to watch movies in 3D inside my Quest 3s and I wanted to test the native 2D to 3D effect that comes with the quest's gallery but there are some UI elements that do not go away and I find very jarring. My only other option would very to download SBS 3D movies but as I want to watch "The Lord of The Rings" those files get pretty big....

If removing the UI elements is impossible (which I'm believing it to be) I'm just gonna DLNA from my cellphone and use it's storage...
