I downloaded the 1.16 beta today and loaded it up . It loaded to the microsoft account login screen with the new 1.16 background and just before I clicked the login button, the screen seemed to refresh. The same screen loaded but it had the black and white minecraft beta background, like the rtx one. I don't know how to recreate this.
