Note: This may be caused by lag due to loading/saving, but seems strange that it speeds up the panorama, not even causing jitter. Quitting the game while in a world in my experience makes the panorama speed up significantly. The video shows it slightly, but if you test this you will see VISIBLY see what I’m referring to. I’m also not sure if this intended behaviour, but here you go!
Steps to Reproduce:
Open world, or save/close world
OR
Quit game while in world
Expected Behaviour:
Panorama has a consistent speed when game is saving or loading world
Actual Behaviour:
Panorama speeds up.
