Same problem here, (though I don't have an issue when in water) and when running, if you touch the side of a block, it slows you to a walk. Also, as far as auto-jump is concerned, it works, but barely. If you end up pressed up against a block, it doesn't work. (Maybe this is how it always is, I don't use auto-jump because I find it annoying, lol!)
