the size of several items is bigger than it should be, but this only happens in textures of 32x32 pixels or higher, depending on the amount of pixels you have (32 64 128 256 512) the affected item will look bigger and bigger this will only be reflected in the players hand and the vast majority of objects that are affected are those that can be placed in the world. these are some of the items that I found and I am not sure if there are any others

(flower pot, item frames, cauldron, hopper, brewing stand, comparator, repeater, chain, the discks, campfire, cake and cane with one mushroom)
