Re: Grace notes cause clef-change positioning problem

[Wilbert Berendsen]

I think this is caused by grace timing. As a workaround you could add a \grace 
s4 in the second staff, the clef change is behind the bar line.

      \grace { a,,8[( a'] } % the trouble is here
      a'1)
    }
    \new Staff = "viola"
    \relative c'' {
      \clef "alto"
      a4 a a a
      \clef "treble" |
      \grace s4 a'1
