Texture problems - Rogues

[Elesme]

I've begun to face many problems with rogues when you use shadow step. In place like Arathi Basin and Eye of the Storm, when the people try to escape, I often use Shadoestep to catch up with them. But then Iuse it and I go into something that look like under the texture and I keep falling for about 10-15 seconds and finally land up in the graveyard. I would, like to know if there s any way of fixing this?

Thanks.

Unfortunately, as far as I know, fixing this from happening with shadowstep, sometimes blink and intercept/charge/intervene is pretty hard or even nearly impossible
