I looked at the issue tracker but couldn't find this one. I was going to go ahead and file a bug directly, but then it told me to bring it up here first, so here I am. It might be related to 721 "Dynamics can collide with notes when applied to cross-staff voices" if it's simply that cross staff notes collide with everything :)
Example code: \version "2.16.2" \score { << \new PianoStaff << \new Staff = "up" { { f''8 e''8 e'' e'' } } \new Staff = "down" { { e'8 \change Staff = "up" g'8 g' g' } } >> >> } When note heads cross to the upper staff, they should cause the upper notes to flip stem directions to avoid collision. _______________________________________________ bug-lilypond mailing list bug-lilypond@gnu.org https://lists.gnu.org/mailman/listinfo/bug-lilypond
