Cursor is moving around when it shouldn't be and messing up the experience

I use a laptop and before late October, whenever I played minecraft bedrock, no matter what I did during the gameplay, the cursor would stay in the same position it was at from the last time I opened a chest, opened chat or paused, which was good but now, the cursor moves around when I'm playing and doesn't stay still. It has been messing up my experience because when I'm clicking to attack mobs, I end up opening other apps or the pause screen and I nearly died more than once because of it while fighting only two regular hostile mobs
