Odd display view when switching modes

This is switching between Write and Engrave modes. Oddly enough, I don’t get this result when I switch to Play mode, then to Engrave mode. The issue persists, not a one-off. I’m running a 4K screen on a Windows laptop, if that’s important.

Not asking for anything actionable as I can work around it, just FYI.

Project file here, though I don’t know that it’ll be helpful. https://www.dropbox.com/s/yvxcn1eidjirr07/Wake%20Awake%20for%20Night%20Is%20Flying_Wachet.dorico?dl=0

We’ve seen this before (and it has been reported here before), but it doesn’t tend to be reproducible from session to session, so it can’t then be reproduced on demand.
