Zed spell cast visual bug

I was playing as Zed yesterday and the spell cast preview for his Q would show up as if my shadow was out after it timed out. This only occurred for the first cast after the shadow disappeared. Happened with my ult shadow as well. Made me confused a little. Unfortunately I didn't get a screenshot of it, but I wasn't encountering it in previous games. I believe I saw it on Piglet's stream today as well
