Wildfire Zyra FPS issues.

So, I recently bought the Wildfire Zyra skin, and noticed that it causes FPS issues, when I used abilities.. Namely, her E, which causes pretty hard FPS drops. I normally play League on 60fps, on LOW detail.. But the Wildfire skin seems to be the only skin I've seen that does this. I emailed support, they told me to post it here. (No ETA when it will be fixed) Was wondering if there's anything I can do at all to get the skin to work.
