When i am playing, no matter if it is in third person or first person, the camera is constantly shifting on its own. Uninstalling and deleting Minecraft completely from my computer has not fixed it nor has the overriding the high dpi setting on the launcher. I only had this problem with this specific version of Minecraft and not with technic launcher or my previous 12.2 minecraft world.

What do you mean with "the camera is constantly shifting on its own"?

The camera even when im not moving is turning on its own. Its like the camera is reseting to the look back up every 5 seconds. I can still move look around but it is constantly just shifting up
