Arpeggio crossing multiple staves overlaps with previous note

[Thomas Shaddox]

I've got a simple arpeggio crossing my two staves, and for some reason the

arpeggio symbol is overlapping the previous note. I have used crossing

arpeggios before without problems, but something about this one is problematic.

I have tried various repositioning techniques described in the Lilypond

documentation, with no success. Any help is much appreciated!

Here's my Lilypond example:

\version "2.12.3"

\include "english.ly"

global = {

  \key f \major

  \numericTimeSignature

  \time 4/4

}

right = \relative c'' {

  \global

  f4 f f8 g8

  <g df bf f>4\arpeggio |

  <f c a>1 |

}

left = \relative c {

  \global

  f16 df' af df f,16 df' af df ef,16 df' a df

  <ef, df' a>4\arpeggio |

  <f c f,>1 |

}

\score {

  \new PianoStaff <<

    \set PianoStaff.connectArpeggios = ##t

    \new Staff = "right" \with {

      midiInstrument = "acoustic grand"

    } \right

    \new Staff = "left" \with {

      midiInstrument = "acoustic grand"

    } { \clef bass \left }
