Minecraft mouse?

I have the problem that when I play Minecraft and move the mouse the mouse reacts but when I stop it it swings a bit.

With F7 you can change the camera behavior. And if it's not this button, have a look at the options.

F8 would be, but as far as I know it has not been possible for a long time.

Know three possible causes for this:

Your game is lagging
Your mouse bugs
You have activated the Cinematic Camera

If your game is lagging when you spin, and that's why it happens, try if Optifine fixes your laggs.

If it's your mouse, try unplugging it and plugging it in again.

If you have activated the Cinematic Camera mode, you can deactivate it as follows:

Assign a key to Escape → Options → Controls → under "Miscellaneous" of the "Toggle Cinematic Camera" function. Then press this ingame.

Thank you
