The dimensions of the JInternalFrame title bar buttons after your fix are 24×18; before your fix they were 28×18. That is the width of the buttons is smaller by 8 and 4 pixels. Aren't these the values subtracted from the width value fetched from Windows?

Adjusted to native button dimensions of 32x18
