Unable to use Liquify filter for "smile" modification in a portrait. GPU is set on in preferences. When the liquify filter is applied I get only a gray screen with indicators for each of the faces identified in the picture, but not the actual image. I have seen some comments regarding support requirements of the graphics required. My system has an Intel(R) HD Graphics 4600 graphics processor; does anyone know if that is compatible with Photoshop CC version 22.3 ?
