Kindred W flickering bug

When I was testing Kindred on the PBE I noticed that when my W was active, and I would attempt to recall, The black area indicator of Kindred's W would flicker for about 1 second. I was able to reproduce this with ease, this only happens in the first second of the attempted recall and it didn't matter where I recalled as long as I was standing in the area of my W. It also doesn't matter how long my W was activated. I am quite sure that this would lead to confusion in games and distract people from the fight. Further testing shows that similar flickering happens when statikk shiv procs or when Kindred ults someone inside the W. It looks like the extra particles inside the ring mess up the lighting (?)

Anyway this is my first report and I hope it's as it's supposed to be, Cheers
