Any SATB score where any instrument have got more than 2 voices and a specific group of notes. I attach my example.
The function involved is the "Copy lyrics to clipboard"
Wherever the score contains instances of notes group like in picture Capture1.JPG, the lyrics of and around that group of notes copied into the clipboard by the above function are messed-up.

Type Wording/Translation ⇒ Functional

Strangly this happens to that score only, at least so far I couldn't find any that behaves the same bogus way?

Another intersting (and possibly related) bug: If a score (or part of it) doesn't have a 1st stanza, but starts with the 2nd (often done in MuseScore 2 for layout purposes, not needed for that in MuseScore 3 anymore), that doesn't make it into the clipboard at all.

Here's one I found, missing the first part (see above) and also missing a single syllable in the 4st stanza (here added back in bold)

  1. Tempus ad est gratiae, Hoc quod optabamus; Carmina laetitiae, Devote redamus.
  2. Deus homo factus est, Natura mirante; Mundus renovatus est A Christo regnante.
  3. Ezechiellis porta Clausa per transitur; Unde lux est orta Salus invenitur.
  4. Ergo nostra cantio, Psallat iam in lustro; Benedicat Domino: Salus Regi nostro.

Here too after the previous stanza has a (mid-word) melisma, this does seem to be related to the bug.

Title copy lyrics to clipboard makes mistakes for voices above 2 ⇒ "Copy lyrics to clipboard" drops syllables if there is none at that spot in the previous verse

So I strongly suspect that a syllable gets lost if the previous verse doesn't have one at that spot, that'd explain both problems outlined above.

I've verified that theory with some other scores of mine, like one that has ony 2 verses (and the Refrain in verse 2, without a verse 1).

It also misses all lyrics that are not attached to voice 1 notes!

This though seems pretty easy to fix (in 3.x, but I assume master to be very similar):

             size_t maxLyrics = 1;
             const RepeatList& rlist = repeatList();

Need to check for unwanted side effercs though

Edit: Hmm, no, seems too simple, with that change voice 2 lyrics are placed at the end, rather than intermixed with voice 1 lyrics. Might still be better than getting ignored alltogether though?

Also it ignores lyrics above stave (a known issue though, marked as TODO), might be easy to fix (in 3.x, but I assume master to be very similar):

Again, need to check for unwanted side effects

Hmm, no such method exists, so would need to get added (in 3.x, but I assume master to be very similar):

The issue with ignoring lyrics above stave is now fixed for 4.1

The remaining original issue should rather get reported on GitHub, as this issue tracker here is being discontinued
