When you have enchanted items, manipulating inventory items makes them very laggy.
If you wear armored enchanted equipment and you have enchanted tools (sword, ax, puckle, shovel) etc and braze the bone meal from the bones, you need close to 1 second.
Using the workbench hid the whole body display a little faster.
I brought all the enchanted items into the chest and craft the bone meal, I did not feel any lag.
It may be the cause of the animation of the enchanted item being lagging.
