How do I fix this 'slidey' cursor and UI?

I've got a basic demo for an RPG/shooter game I'm working on. Everything seems to be going smoothly.Except as you can see when you keep the mouse still and move using WASD, the cursor 'slides' around a little bit. It also does this with any HUD elements I try to add, which is a lot more noticeable and hugely annoying. How can I make it more still, so things which should be stationary don't trail around?

Hard to say unless you can share the .capx.

Like Xavier says - capx...

but is everything on the same layer?

I also notice there are times when the arm or whatever he is swinging around or whatever it is, is in front and other times it is behind...

Nevermind, I fixed it. I set the UI parallax to 0 and changed the cursor to a sprite instead of setting a sprite to the location of a cursor.
