If you didn’t scale up the vector layer then there is absolutely no reason/need to switch on its Continuously Rasterize.
Another thing to note is that distortion effects with position parameters work on a layer’s innate dimensions. However, if you rasterize the vector layer then such distortion effects work with the composition size.
There is actually a mathemathical solution to your issue which entails moving each parameter based on the scaling factor that you applied to the layer – assuming that you had changed the layer’s scale prop.
