High Noon Jhin vs Fiora visual bug

Hello, while playing game today against fiora, she was top, i bot, when we did have skirmish with her, i think a lot of us used skills against her and she blocked everything, but after that my icon for W glitched, it was on her to the end of game, it was only visual bug, i didnt rooted her, but it was confusing when i can hit her and root or when not, circle is a lot brighter then normal
