Bug:
When moving items in inventory the items will lag behind the mouse.
How to reproduce:
Pick up an item in the inventory and move the mouse around.
Expected Behavior:
The item will cling to the mouse until placed back in the inventory, similar to Java.
Actual Behavior:
The item will lag behind the mouse only catching up when the cursor stops, if the mouse clicks a slot before the item catches up, it will snap to that slot, which looks strange since this lag could be interpretted as an animation.
