Version 1.4.6 - Minecart moving in clockwise direction appears off track at about the 6:00 position and returns to the track at about the 12:00 position.

Related to MC-4057? It's also a problem with minecarts turning...

No, unrelated. This is about carts appearing off the track while still being ON them.

You are correct Anon Ymus - in my example the minecart is still "on the track" because it keeps going around.

This seems to happen when a (storage?)minecart is moving while one is quitting the game (SSP).

The minecart is being displayed at (x,y,z-1) when being at (x,y,z).
Illumination is being computed referring to (x,y,z-1) (i.e. gets black when moving next to a solid blocks).
Apart from that the cart follows the rail quite normally: The interaction with turns, acceleration tracks, and sensor tracks is normal.

Can confirm in 23w06a and 1.19.3

Experiencing repeatedly (very, very repeatedly) in 1.20.6.  Not just visual, also catches on mobs and other carts.  While in motion, passes through most (but not all?) solid blocks unobstructed, will also float adjacent to the track it's allegedly on.  Also causes incorrect interactions with powered rails and detector rails; carts will sometimes not be detected.  The glitch is currently making it extremely difficult to use Minecarts in the game.

This might be a duplicate of MC-170907 and fixed now in 1.21 Pre-Release 1

1.21 Pre-Release 2: when reloading the chunks, if one minecart unit (of for example 10 minecarts), some minecarts might bug into each other. This is as if one minecart is moving, but with a way darker shadow.

From my testing and observation this past week, this seems to be fixed with the experimental minecarts from 24w33a. I will be adding the 'experimental_minecarts_fixed' tag, please feel free to remove it if a new case comes up proving that this is not fixed yet.

As an example, here is a tick sprint with minecarts on powered rails:

Previously, the minecarts would have cut around the corners going over blocks off of the rails, this no longer occurs.
