This is a long-standing bug in Core Graphics.  The Mac port contains
an info node suggesting some workaround:

     Also, synthetic bold looks thinner if the background is darker than
  the foreground and the LCD font smoothing is turned on.  In such cases,
  you can turn off synthetic bold for particular fonts and use
  overstriking instead by customizing the variable ‘face-ignored-fonts’:

       (add-to-list 'face-ignored-fonts "\\`-[^-]*-monaco-bold-")
