We investigate the growth of operator size in the Lindbladian SYK model with q-body interaction terms and linear jump terms at finite dissipation strength. At weak dissipation, the evolution of operator size displays a quadratic-exponential-plateau behavior. We also find that the uncertainty relation for operator size growth is saturated at large q, leading to a classical dynamics of the operator size growth with dissipation.
