We investigate the high-temperature phase of QCD using lattice QCD simulations with N f = 2 dynamical Möbius domain-wall fermions. On generated configurations, we study the axial U(1) symmetry, overlap-Dirac spectra, screening masses from mesonic correlators, and topological susceptibility. We find that some of the observables are quite sensitive to lattice artifacts due to a small violation of the chiral symmetry. For those observables, we reweight the Möbius domainwall fermion determinant by
