Wildshards bug? imput lag issue

I use Fireball in a setup with Scattershot, Unleash, Wildshards. I just put Wildshards in and as soon as I put it in it causes an incredible lag input (around 500-1000) for the duration of the proc, then everything goes back to normal. And so every time. Cool but you can't play with it because it's easy to die, the game screen freezes for me but they still beat me. I don't know if it's because of the last patch or it's been like this from the beginning. For now I have to change the support gem.
