Re: Bad clef change collision when alternating piano staves

[Pierre Perol-Schneider]

Oops, sorry, too fast reading...

How about :

\version "2.19.22"
\new PianoStaff <<
    \new Staff = "RH" \relative a' {
        \clef treble
        a8
        \change Staff = "LH" \clef treble a_1
        \change Staff = "RH"              a
        \change Staff = "LH"
        \tweak X-extent #'(0 . -2)
        \tweak X-offset #-3.3 a_2
        \clef bass
        \change Staff = "RH"
        \tweak X-extent #'(-7 . 1.3) a
    }
    \new Staff = "LH" \relative a, {
        \clef bass
        a8 s4. cis8_3
    }
