Is there a good way to force Solid to fully rerender a component when its props change?

I need to do some procedural computation on my props (I'm trying to draw grid lines based on a size and transformation), so I pretty much need a full rerender whenever the props change - is there a good way to do that?

Have you tried createEffect? If the lines themselves aren't signals I think it would be good solution to take props you need inside createEffect and there do redraw.

function Component(props) {

let gridRef;
createEffect(() => {
  gridRef.drawLines(
    props.size, 
    props.transform
  );
});

return <Grid ref={gridRef}></Grid>
}

function Component(props) {

let gridRef;
createEffect(() => {
  gridRef.drawLines(
    props.size, 
    props.transform
  );
});

return <Grid ref={gridRef}></Grid>
}
