That's expected behavior. react hook form would need to flush down a re-render at the root (useFieldArray) of your form.

but other all controller field component all rerender ，poor performance

[silverWolf818]

many no change component render poor performance

I understand there is no problem with component rendered in useFieldArray returning fileds , but other fields that are not in this scope should not be rendered
