Mobs visually sinking through solid blocks

3rd person view reverts to 1st person view if head inside a block (corner a one block wide tunnel in a minecart, ride on a horse through a block, piston...)

"/spawnpoint" command fails directly on Pressure Plates, Cobwebs, Signs, Open Fence Gates

Creating or loading a singleplayer world shows the main menu for a brief second

Fall damage is ignored for a couple of seconds when reloading into LAN or singleplayer worlds

The portal travel sounds travel.ogg / trigger.ogg swapped / played at wrong time

Most text boxes / chat / scroll bars revert when the window changes size, fullscreen mode is toggled, or fullscreened game is tabbed into

Chunks do not delete properly remaining in a newly created world if the same world name is reused

The armor bar sometimes obstructs the view of the very bottom of the map

Arrows first bounce back then appear at correct location

Lily pads can be placed intersecting entities

Compass points wrong direction after returning from nether

Zombies only fight back against players

Villager can have all trades disabled

Arrows trigger wooden buttons without actually touching the button
