We report on advances in the non-perturbative determination of the ratio $Z_\mathrm{S}/Z_\mathrm{P}$ of the scalar to the pseudoscalar renormalization constants in three-flavour lattice QCD with Wilson-clover quarks and tree-level Symanzik improved gluons. The computations are based on the Ward identity approach, using Schrödinger functional boundary conditions. Our results for $Z_\mathrm{S}/Z_\mathrm{P}$ cover a range of couplings along a line of constant physics with lattice spacings of about $0.09\,$fm and below, relevant for phenomenological applications such as the calculation of renormalized quark masses.
