Hi Leo, thanks for testing. I'm still on it trying to improve things... There's https://gitlab.com/lilypond/lilypond/-/merge_requests/998 on the way (thanks Jean). As a result (among others) cross-staff broken glissandi now work as expected. Ofcourse I will need to adjust the stemmed glissandi for it, once it is released. For now: Moving NoteHeads depending on their 'transparent property is not that bad. You coud invent a new property or use a subproperty of 'details (less invasive). Though, this is a first thought, the final implementation will differ anyway ... Regarding the TextScript, this is caused by setting cross-staff. A minimal (without any glissando-code) #(ly:set-option 'debug-skylines #t) { \override Stem.cross-staff = ##t \voiceOne b'4->-"t" } Switch between #t and #f In any case, coding stemmed glissando turns out to be a very hard ... Cheers, Harm
