			In singleplayer before 12w18a, items dropped from the player or blocks would display at the correct location without any corrections or errors. After 12w18a's server merge, the client still kept its high precision velocity calculation instead of conforming to the servers low precision velocity calculation. This resulted in item drops being misplaced or snapping from its intended location due to server and client mismatch of precise coordinates.

			An attempted fix was made in [[Minecraft:1.8.1-pre1]], which had no effect. In [[Minecraft:16w06a]], a change to entity movement partially corrected the block edge miscalculation issue in regular gameplay scenarios. An undocumented change occurred in [[Minecraft:16w32a]], mentioned by [[Minecraft:Jeb]] on the issue tracker<ref>''Jens Bergensten - It's fixed to the point that I can't reproduce it any more. Please update the bug report after the first 1.11 snapshot if you find a way to reproduce it. Obviously the items will jitter slightly depending on client-server lag issues, but items should no longer appear in the wrong locations.''</ref> and Reddit<ref>https://www.reddit.com/r/Minecraft/comments/4w5qla/mc4_the_bug_of_item_drops_sometimes_appearing_at/d66vgxd</ref>, that fixed the correction snapping issue, In [[Minecraft:26.3 Snapshot 1]], all remaining server/client mismatches of item coordinates were finally fixed, closing the issue after 13 years of being open.<ref>{{bug\|MC-4\|\|\|Fixed}}</ref>

	Teleporting entities originally snapped straight from their old position to their new position, with no visible movement between them, as would be expected from a teleport. However, client-side interpolation is not turned off for teleporting entities in multiplayer (and singleplayer after 12w18a), causing them to instead appear to quickly travel in a straight line to the new position. This was reported on the issue tracker and closed as "Works As Intended".<ref>{{bug\|MC-303560\|resolution=WAI}}</ref>		Teleporting entities originally snapped straight from their old position to their new position, with no visible movement between them, as would be expected from a teleport.
