Kelvin's Ice Path has a very weird feeling since last patch

When using the ice path it feels like the path isn't created fast enough for how fast you can run. You can kind of see this on in the replays (ie. 34672753) and I will try to get a video in game but I cannot seem to recreate it in either a bot lobby or in hero testing, it appears to be only in game, maybe to do with ping or server response time.
It makes using the path almost unplayable and seriously janky which it never has before

This isnt even the worst example from this game but its the only one I captured, what I did notice is that when moving around your movement speed would drop from 17 to 8.8 constantly.
