Exactly as the title says - crossStaff works for all stemmed notes, but quavers which are not beamed lose their flag. I have resorted to merging in an extra note to get the flag, as in this example which shows the problem and my hack:
\version "2.23.3" \score { \new PianoStaff << \new Staff { \clef treble \crossStaff {<e' c''>4 q8 r q q r q | << q \new Voice { \voiceOne c''8 } >>} } \new Staff { \clef bass \stemUp \crossStaff {<c g>4 q8 r \autoBeamOff q q r q | q} } >> \layout { \context { \PianoStaff \consists #Span_stem_engraver } } } This problem does not seem to be affected by any other settings - especially (as shown in my example) not autoBeam[On]Off. The problem is also present in the older versions of LilyPond at LilyBin.
