playback tempo changes if hiding stave setting is changed

Hello,

I've noticed a problem with the playback tempo. Every time I make changes to the 'hide stave if empty' setting of instruments, the playback tempo slows down at a random point of the piece. If I save, close and reopen the document, the tempo behaves normal again till I change the 'hide stave' setting again.

This happened with more than one document recently.

I've also had the playback tempo speed up to 6000+ bpm earlier when I was setting up some repeats with voltas. I can't quite remember if I also changed some 'hide stave' setting in between, but reopening the file helped temporarilly.

Kind regards
