[Bug] Unexpected extra mouse input

[Phoupraw]

There is often unexpected mouse input in my client, such as unexpectedly quick moving items from chest to player inventory, unexpectedly rotating player facing direction, and so on.

My friends meet the same bug, too, which means it is not an only case.

This bug happens both in 1.7.0 and 1.7.2. It wasn't tested in other versions.
