I attach an example which fairly reliably demonstrates the issue.
- Go to bar 570
- Try to extend the note length to the end of 577 - I used
Shift+Option+Rightin 8th note increments
- If you are successful, try shortening the note back to its original length
By this time you should see the problem: The selected notes start flashing; displaying and disappearing; Bar numbers disappear; Dorico is unresponsive.
I have tried this particular example on the desktop, and it’s not an issue there.
This is not an isolated example of this “flashing loop while extending” but at last I found one that fails consistently on this iPad (iPad Pro 11" 2nd gen) after I pared down the complete project.
