It is a dropdownbutton, the right edge of the menu and the right edge of the button are right-aligned. But there is 10px to display the shadow!

The picture below shows a contextmenu:

I don't get what's wrong here.
Could you be a bit more specific on what you think should be changed.
Sometimes it's better to explain how it should be instead of saying it's wrong. ;-)
