Comment #6 on issue 2328 by address@hidden: Ledger lines in PNG output  
have white interior
http://code.google.com/p/lilypond/issues/detail?id=2328

The problem is really with ly:round-filled-box.

This has a white triangle in PNG output with unpatched ghostscript:

{
  \override Staff.Clef #'stencil = ##f
  \override Staff.TimeSignature #'stencil = ##f
  \override NoteHead #'stencil = #(ly:round-filled-box '(-2 . 2) '(-1 . 1)  
2)
  b'1
}

But this doesn't:

{
  \override Staff.Clef #'stencil = ##f
  \override Staff.TimeSignature #'stencil = ##f
  \override NoteHead #'stencil = #(ly:round-filled-box '(-2 . 2) '(-1 . 1)  
1.999)
  b'1
}
