Staff spacing in galley view

I wonder if this is a problem only on macOS. I repeated your test using the same versions of Dorico 4 and 5 on Windows, and there was no difference in the width of the text with the font stretch set to 200%.

Thank you for your answers! So there may be a bug with stretching. Let’s hope that team will fix it. I have mac but I have Dorico also in my Windows laptop so I’ll explore that later with that.
