Here’s a weird one: In some multirests I get 5 dark black horizontal lines (attachment Multirest Bug).
The three different examples I’ve come across had differing numbers of bars in them. The only commonality I could see in them was that all were on the top staff of page 2 of a part.
Changing the number of bars before or after them on the staff didn’t help, but re-staffing so they were bumped back to the previous page made them behave properly.
An additional buglet is that in at least one instance, a single bar rest got a multirest number (attachment Multirest Bug 2).
Not complaining, just reporting…
