[BUG] High Noon Yasuo visual bug

The server i play on is EUNE but i saw other forum and reddit threads and i'm sure it's not only in EUNE. The bug is sometimes (mostly late game) when you use Q with Yasuo he switches to another running animation making his hat go under his head or something like this (i'll upload a screenshot below). I am not sure how you can actually represent the bug, but i'm sure it happens every time he switches to the other running animation. Here's a gif link so you can see better http://gfycat.com/WeirdYearlyGrackle the video is old but the bug is the same and it's still not fixed. Please upvote so someone from riot can see it, thank you.
