      The bug

      Using /clear while an inventory is open and you are holding an item with your mouse causes an inventory desync and turns this item into a "ghost" item. You can place it in your inventory, but using it will fail in Creative mode and in Adventure and Survival mode additionally removes the item.

      Expected would be that /clear successfully clears the held item client-side as well.

      How to reproduce

      1. Put a repeating command block down with 
        /clear @p torch
      2. Switch to Creative mode 
        /gamemode creative
      3. Grab a stack of torches for example from your Creative inventory and put it in your hotbar
      4. Try placing down torches
        → The torches are not placed

      Code analysis (outdated for 1.13+)

      The following is based on a decompiled version of Minecraft 1.8 using MCP. All method and class names are the ones used in the decompiled version.

      The reason for this is a piece of code in the public void processCommand(ICommandSender sender, String[] args) method of the net.minecraft.command.CommandClearInventory class that only updates the held item once the /clear command was used, if the player is not in Creative mode:

      public void processCommand(ICommandSender sender, String[] args) throws CommandException
{
	EntityPlayerMP var3 = args.length == 0 ? getCommandSenderAsPlayer(sender) : getPlayer(sender, args[0]);
	
	// ...
	
	if (args.length >= 2 && var4 == null)
	{
		throw new CommandException("commands.clear.failure", new Object[] {var3.getName()});
	}
	else
	{
		int var8 = var3.inventory.func_174925_a(var4, var5, var6, var7);
		var3.inventoryContainer.detectAndSendChanges();

		//This prevents the update
		if (!var3.capabilities.isCreativeMode)
		{
			var3.updateHeldItem();
		}

		//...
	}
}

          CreeperMagnet_It was always cleared on server, but client was not informed about it. So fix was to trigger update.

          Just wondering, how exactly was this bug fixed? Can command blocks clear & detect items 'on the mouse' anymore, or not? Or is it a new slot or something of the like?

          Whenever you open a chest, furnace or any other objects like that, it updates and removes the torches.

          For any map creators, you could use this while it lasts. It could create a false adventure mode cause you can add nbt to items and specify what type of items for this to work on, also, dropping the item just removes the item from your hotbar and doesn't actually drop them. But although it could be used like that, it is a bug and should be removed.

          Similar issue with nether stars not changing name color after clearing and being given a new one immediately in 19w06a.
          And this time no comment updates

          Yeah ghost items in 19w04b, but not directly related to /clear, just ghost items in general. Specifically when an item is dropped and given back immediatly by /give like the repeating chain below:

          /execute as @e[type=item,nbt={Item:{id:"minecraft:gold_ingot"}}] at @s run scoreboard players set @p temp 1
/kill @e[type=item]
/give @a[scores={temp=1}] minecraft:gold_ingot
- Other stuff inbetween here
/scoreboard players set @a[scores={temp=1}] temp 0

          (temp is a dummy type scoreboard)

          I really need this fixed. My inventory won't update if I replace a slot too quickly. The only workaround working for me is to clear my slot with something else to refresh it before replacing it with the actual item. Can't do this in any case however.
