As has said, if mesh size is enough to capture liquid-gas interface accurately, VOF is usually unsteady, so you should consider unsteady simulations.
If unsteady simulations exceed your available computing power and/or you want a general idea of what is happening, an alternative is to decrease the relaxation factor of the volume fraction equation.
