Hi all. I've encountered a problem when using \afterGrace and cross-staff notes. It may be related to these issues:
https://gitlab.com/lilypond/lilypond/-/issues/6171 https://gitlab.com/lilypond/lilypond/-/issues/6197 Here is the MWE: %%% \version "2.25.7" rightHand = \relative { c''1~ \startTrillSpan | \afterGrace 15/16 c1 { b16[ \stopTrillSpan c] } | c8 g e c \change Staff = "lower" g e c g | } leftHand = \relative { \clef bass c4 c c c | c4 c c c | s1 | } \score { \new PianoStaff << \new Staff = "upper" \rightHand \new Staff = "lower" \leftHand >> } %%% This produces several programming errors: programming error: cyclic dependency: calculation-in-progress encountered for VerticalAxisGroup.adjacent-pure-heights continuing, cross fingers -- Knute Snortum
