I found a reproducible case for the screen jumping bug.
- Open the attached project.
- Switch to Galley View and zoom in.
- Select the notes in the double bass staff (measure 19).
- Copy the notes.
- Paste into the bassoon staff at the same measure.
- Scroll down to the double bass staff.
- Select the notes again.
You can get similar jumping effects with paste, undo, scroll, select, even in Page View.
(EDIT: This only occurs if “Follow selection changes on undo and redo” is enabled.)
