Sometimes randomly when I'm running, walking, or jumping, my character just starts repeating that action without input.

For example if I were to walk forward, my character would start walking randomly into walls in different directions, or if i were to jump, my character would keep jumping.

Sometimes it even effects mining blocks. I was mining stone one time and after i stopped pressing the mine button, my character just kept mining what was in front of me, even without input.

This only effects Minecraft too, when just using my computer for other stuff, the problem doesn't occur.
