The bug
When you go into 3rd person view while using a spyglass, it still plays the animation where the FOV increases and when you go back into 1st person view, it plays the animation where the FOV goes down. This can be annoying when changing perspectives very often while using a spyglass.
How to reproduce:
Hold a spyglass in your hand
Hold down right click
Go into 3rd person view
❌ It plays the animation where the FOV increases, instead of instantly increasing the FOV without any transition
Go back into 1st person view
❌ It plays the animation where the FOV goes down, instead of instantly decreasing the FOV with any transition.
Expected result: When changing perspectives, the FOV should instantly change without an animation.
Can confirm. It's as if you are zooming out/in.
