Wrong background of NSButton

[VoidFaceless]

create NSButton in IB, set borderless and image, and image position to image only. In window it looks good. after place it to title bar, When click on it, there is white background, not transparent as in the window. Am I wrong?

I think this will help you fix the white background problem

[button setBezelStyle:NSRoundRectBezelStyle];
[button setButtonType:NSMomentaryLightButton];
