Moving mouse while closing a menu causes the camera to snap in the direction of the mouse.
To replicate easily, set mouse to a low sensitivity. The bug does appears in higher sensitivities, but it requires better timing, as it seems like the menu needs to be closed while the mouse is moving in the menu.
Bug affects Settings menu, Inventory menu, and Crafting table menu.
Enchantment table menu, Villager menu, Potion menu, etc. were not tested.
Bug shown in the video.
I apologize in advance if this is a duplicate bug report.
