I am currently having this "input glitch", although minecraft itself is running smoothly. As you can see in the linked video, it happens with the mouse but also the keyboard, so that when i move the mouse it is very jittery, it recognizes my movements but only processes them slowly, and the same goes for my keyboard. For instance when i try to fly in creative mode (via pressing space twice) it wont always do it the first time, so i have to do it a few times in order for it to start me flying.
This has been going on for a while and since then has only gotten worse.
