Akali's w not showing up properly

I was playing akali in aram and her w was messing up. It wasnt a full formed circle. It would shrink immediately, disappear, and reappear as a big scatter of partial clouds and shrink back down and repeat. The circle would completely disappear after the first half second of messing up and wouldnt come back. The clouds would stretch to the edges of my screen and be all over the place. My friends saw saw her usual ring on their screens but it was acting strange on my end. I couldnt use her w at all.

Update: looked back on game replay and her w appeared just fine.

Someone else has reported this a week or two go and it still hasnt been fixed.
