Item drops sometimes appear at the wrong location

Minecarts that occupy the same space maintain their momentum

Blocks don't retain their names, enchantments, or attributes after being placed and picked up again

Mouse buttons block all inventory controls that are not default

Detector Rail switches junction before Minecart passes detector (happens only with minecarts of certain speed)

Powered rails do not update when additional power sources are added or removed

Ocelots do not spawn naturally on peaceful difficulty in jungle and bamboo jungle biomes

White stitching on polygon edges / White lines or black dots between blocks

Axolotls, endermen, and enchantment glint animations continue playing when the game is paused

Ender pearls can teleport entities inside solid blocks

Beacons keep higher level effects when partially destroyed

The Unicode font is hard to read from a bit of distance

Enchantments from items held in the main hand are applied to other items when entities are killed

Detector rails do not power adjacent powered rails upward on slope

Entities floating in water don't receive vertical knockback upon being hit

Block cracks don't appear on the lower halves of doors when zombies are breaking them

Large amount of chests and shulker boxes creates FPS drop

Text can extend beyond the edges of some GUIs

The white markers on maps created in the nether or end dimensions don't disappear when viewing the maps in the overworld until the world is reloaded

TNT minecarts sometimes detonate when going around corners

Large amount of fences impact performance

Two-by-two arrangements of jungle or spruce saplings cannot grow when there are adjacent blocks located north or west of the sapling formation

Mycelium and podzol cannot be tilled with hoes

Minecarts don't slide on any sort of ice

Powered mechanisms react when receiving a 0 tick redstone signal (existence of micro-pulses in general / inconsistent block update 'algorithm')

Block cracks remain on blocks in adventure mode when losing focus of them
