Every tool in hand begins to shiver like the attack button is on autofire.
No third party mouse driver, no joystick or gamepad involved.
Never happened before, only 18w19a is affected.
It is impossible to mine blocks or fight properly.
Picking up an item (for example: a tree seed) and destroying weak blocks is possible.
Addendum:
Possibly the same issue as MC-129268

I noticed this happens with a every item that has been damaged. (when the Damage tag exists). It also happens with food and potions. It doesn't happen with chorus fruit or ender pearls.
THIS bug right here... makes the snapshot unplayable in Survival. More than confirmed at this point, tools don't appear in the player's hand, right or left, and blocks can't be broken. I managed to harvest 1 Cobblestone before my wooden pick wouldn't mine any more and shift-clicking it into my inventory from my hotbar 'clones' the pick. They aren't usable, but it does fill my inventory if done enough. Manually taking the item again 'deletes' the 'clones.' Back to manually adding ores to the furnace I go!
