When combine items, game get delay for 0.3~0.5 seconds.
So, I can't make item fast.
For one set item, I need almost 1 minute.

And, when move items to another slot, it also sometimes get delay.

Please fix it or add function to combine one set items.

Addition.

condition for bug.

 - To combine item.

 - To open inventory (player inventory, crafting table etc.)

 - to throw out items

If I combine item as fast as I can, frame rate become 2.5 fps.

On that time, game shortly delay, but time in game is not stopped.

If I craft items by one set as using USB keyboard, delay increase as twice or more than.

After 1.11.0.1.beta update

It was not resolved, but when using stone cutter, this bug doesn't occur.
