Capo parentheses scaling issue

Here’s what I’m getting with my defaults:

I think Dorico is scaling the parentheses to the slash size in your lower example though, and it seems a bit larger than the other elements, so is getting an exaggerated result. Since Dorico doesn’t really offer much control over the slash size and positioning, I created a doricolib file that will add a functioning “Chord Symbols Slash Font” Font Style. I posted it in this thread not too long ago.

If I increase the size of the slash, I get an exaggerated result like you are seeing:

The doricolib file also allows default scaling and Y positioning (positive values are down), so you might want to try playing around with it and seeing if you find settings that work with your fonts.
