Jittery Screen while turning or hitting blocks in creative

I've come back to Minecraft recently, but there seems to be this bug now that's giving me headaches. Before, the camera movement was relatively smooth. When I watch youtube videos of Minecraft, it looks smooth. But when I play it on my computer, it doesn't look smooth, It's jittery. I also have a laptop and tested to see if it happens on there, which it did not. I also tried changing my mouse to see if I had a bad mouse or something, which did not fix it. Deleting Minecraft and reinstalling did not fix it, neither did reinstalling Java.

Here's a video showing what I'm talking about.
