Glitchy mouse movement

So, I loaded up a fresh, normal Survival world today on Minecraft with the normal settings apart from Friendly Fire off, Immediate Respawn on and all the experimental features on. I have no mods installed. Then, when I got on the world, sometimes when I moved the mouse my view would sort of shudder (I can't do a video as the PC doesn't meet requirements), like when it would go back a little. At one point, it even turned the camera view about 90 degrees. Nothing wrong with my mouse or surface, as my mouse is working fine when I navigated to the web browser, opened up the bugs page and all that stuff.
