Button image left shift on focus?

Facing issue image inside button shift slightly left on focus.

Make sure focusFootprintBitmapUri and focusBitmapUri are set to an images that is exactly the same size even if that means setting the footprint bitmap to a 100% transparent image if you don’t want something displayed.

Still facing same issue and on focus of button there is small dot.

Let me know how to remove small dot on focus of button.
