there's a wierd z fighting glitch i found after installing the latest 1.15 update
it affects shields (both enchanted and unenchanted), enchanted swords and armour boots and leggings (though texture z fighting on armour boots and leggins is an old bug which has not yet been fixed, and these do not happen on bedrock edition, because the legs of the player is constantly animated)
recreating this bug is extremely simple, just sleep in a bed with shield(enchanted or unenchanted) equipped
i know i'm being nit-picky here but, in my opinion, glitches like these and https://bugs.mojang.com/browse/MC-160343 should be eliminated before updating and adding more content to the game
