Clematis leaves having white lines

Question

On the below picture you can see some of the leaves of my clematis Hagley Hybrid having light grey lines of unusual pattern. I am afraid that if don't do anything, this might spread to other leaves. The plant looks healthy and has a lot of blooms. Can you please help me to identify the root cause and suggest a potential treatment?

Thanks
