Harmonics, display

I get this result when entering a whole note + (artificial) harmonic:
Harmonic_Dorico
It looks quite crooked but the harmonic note cannot be corrected independant from the main note. Is there another way to make this look better?
Thanks!

I agree that this doesn’t look good, and indeed modifying the diamond noteheads used for harmonics (or at the least making Dorico choose a different kind by default) is on my list of things to do on a rainy day. I think your best bet, assuming you have Dorico Pro 3.5, would be to edit that notehead type yourself in Engrave > Notehead Sets to something that you like the look of more.
