That's the default behaviour of Button control, if you want to avoid it you have some options:

1. Use another control like textBlock and use OnMouseLeftButtonDown/Up

2. Customize the template of your button: See the link bellow, this is default style of a button, you can copy/paste the Template part and modify it as you want. (You need to play with different visual states)
