i'm also having this issue, initially i thought it was because i was using moonlight but after testing it just seems to be minecraft itself.

Same here:

when using /clear and /give in the same tick, example, you have a /clear command block, and a /give command block, the inventory is confused, and ghost items are created. another item has to be moved into the slot that the item is in, so that the item will reveal itself.

steps to reproduce:

make sure that inventory is empty exept for dirt.
impulse command block: /clear @p dirt
chain command block: /give cobblestone
ghost cobblestone should now be in the first inventory slot.
attempt to place another object in the first inventory slot to reveal.

Note: an automated temporary solution is to use a repeater to delay a tick, and give the player an item, and then ue another repeater, and then remove the item.

example:

repeater
Commandblock ( /give dirt 1 )
repeater
Commandblock ( /clear dirt 1 )

press enter does not catch up for me.

Same here, also noticed that you can no longer navigate the text with control+arrow. this is very annoying. Windows 10, 12.2.5
