Expected behavior*_When I UNcheck a checkbutton I should be able to clearly see the unchecked status._*Actual behavior*_When I UNcheck a checkbutton the focus effect (darker background and border) makes it hard to see that the button is unchecked. I have to click outside the form for the focus effect to disappear and see that the checkbutton is actually unchecked._*Resources (screenshots, code snippets etc.)

I click twice and it still looks like it is checked because of the focus style.This is very confusing behaviour for the user.
