As you can see on the picture the buttons aren't exactly clean on the bottom and right side.
Does anyone know if this is only going to be like this in the beta or will it be like this in retail also?
I'm not sure if it's anything that will be addressed anytime soon, but if you wanted to you could use a circular cut-out tool and cut it just a tad bit larger and get it closer to a circle. I was able to cut square buttons holes when I was playing around learning the basics of it all.
