Arpeggio/Glissando's Stretch Speed can't be changed even after manually setting the speed.
Here's my video which I used MuseScore's "Send to YouTube" feature : https://youtu.be/e9R96jLToaM
Compare the the Glissando at 0:10 and 1:49. The one at the beginning is quicker than the one at the end. I setted the speed at 0.50 yet the one at the end sounds like 1.00.
I did delete the Glissando and manually label and set it again but it still didn't work. Is there a way to overcome this bug?
