Settings are jittery. Unless you Close all apps and start minecraft fresh wait for it to fully load then it's gonna run jittery. Example open minecraft background freezes then comes up to speed. Click on setting might be noticeable through transition. Scroll down to video or something freezes then goes then freezes then goes. Same thing when you're in video scrolling.
