  We revisit the scalar potential in the Litim-Sannino model. We compute for
the first time the full quantum corrections to the classical potential and show
that they significantly ameliorate the stability analysis at the UV fixed
point. The quantum effective potential is computed at two-loop order and the
numerical precision is further improved using resummations and parameter
optimisations. As a result, we find a consistent widening of the UV conformal
window across various approximations.
