[MC-86619] Hand moves up and down when switching between empty slots

When scrolling between two empty slots in the taskbar, the hand moves up and down, just like the viewmodel would when switching filled slots. Normally, the hand should not move at all when switching between empty slots.

Can confirm.

Actually, more likely intended now due to MC-86624

This has been fixed in the b snapshot.

This bug in 17w06a appears if you load the saved empty toolbar and do not fill it. Eliminated if a toolbar fill something and then removed again (sorry for the spelling mistakes, if any)

I noticed that this error only occurs if the last toolbar was empty (that is, you need to load twice as a blank toolbar)

Sounds like a separate issue, please create a new ticket.

JUE13 2017-04-06T05:57:12Z

This bug appeared again in 17w14a. To reproduce this bug, restart the world and scroll through the empty hotbar. After a while this bug will disappear.

JUE13 2017-04-19T07:47:47Z

still in 17w15a

Also occurs when switching from the same item (e.g. fish -> fish), which did not occur in previous versions.

Occasionally stops happening. Loading a saved creative toolbar always makes it start happening again for me.

@@unknown:

It should be noted that this happens only on a remote server or LAN connection (excluding the host) because locally, within the same client, packets are transferred in-memory, thus the map decorations don't get serialized and no information is lost.
The in-memory transfer is also the cause for MC-86619.

The hand movement is happening in singleplayer as well.

@blobjim Here it actually only affects singleplayer (and LAN game host). The effect is reversed. On a server, network item stack serialization "fixes" the empty slots and they don't display the animation when scrolling.

Affects 18w21b

Seems to affect 18w30b; see MC-135041.

Kraif 2018-08-28T16:23:20Z

Confirmed for 1.13.1.

DelimanCZ 2019-09-05T12:19:37Z

This is the most annoying bug.

bl4ckscor3 2019-11-14T17:12:10Z

Seems to be fixed since 19w46a.

tryashtar 2019-11-15T00:20:10Z

Also looks fixed for me. Will resolve, please comment if you can still reproduce

violine1101 2019-11-16T18:24:16Z

Yup, seems to be fixed! 🎉
