Hello, I have a small error, when I am in full screen in minecraft for some reason the screen is moved to the right making almost not see what I have in my hand. Thanks for your attention.

What is your fov

89 of fov, but that does not vary in the position of the hand, apart from what happens to me in all versions, just in case it works, I play in windows 10

Please provide a screenshot with the debug screen enabled (hit the F3 key) demonstrating the issue.

the first is fullscreen and the last minimized

This is intentional. The game compensates that way for the different aspect ratio of the game (4:3 vs 16:9).
