So, I checked out the create new world button in the menu, to see what changed. When I clicked on the Game Rules button, I noticed that the text of the option at the botton of the screen, where the other buttons are, showed u; through the button. I know, this is a small bug, but it would be a quality of life change for me. In game, there is also the fact that if you have an enchanted book in a chest, if you scroll over it with the cursor, you will see the enchantments but also the numbers of the items in the chest that are supposed to be behind the enchantment area (sorry, idk what to call it).
