Description

Issue type

File corruption

Description with steps to reproduce

In a new score with two identical instruments:

  1. Enter note input mode on a staff
  2. Turn on stave sharing (create stave sharing groups)
  3. Enter a couple of notes
    Result: No notes are drawn on the shared staff
  4. Turn off stave sharing
    Result: Rests become visible unfull bars. These cannot be deleted with range or single/list selection (although the bar itself can with Cmd+Del). Score corruption error when attempting to save file.
