[Gameplay] weird shadow on Lulu's pixie.

I have nearly every Lulu skin, and I love to play her. There is however one major issue on her. As you walk around on Lulu and her pixie bobs around there is this horribly distracting glitch that bobs over her pixie changing the shade of it as she moves. It looks like a defined line that if the pixie drops under the line its really dark, if it is above the line its the correct tone and color. As it bobs between the two you can just see a line going through the pixie. I use Medium quality on Character models, and low on everything else. The same bug happens on every skin for me I have every skin , except wicked so can not vouch for that one. Winter Wonder Lulu has an additional bug on the wing of her flying poro it just glitches while the other side flaps. Included some quick screenshots to show what I mean. I hope you can fix this glitch before Star Guardian Lulu comes out because I am stoked for it.
