Object Glowing Red when I move my mouse over it

I've been playing around with the iray shaders and for some reason. One of my objects glows red when I move my mouse over it. It's supposed to be black and I don't know why it's doing this
Anyone know why?

I should mention the material i'm using is Rubber-Studded Black. And it seems to be the only one that is doing this.
This is a known issue.
So no fix for it I take it?
Not yet, no - although it may be worth checking the current Public beta. It didn't seem to affect me so I can't say whether the beta is fixed in this regard.
It only happne in the Preview. While annoying (somewhat), it won't affect the final render. Hover over a different object should fix it. Maybe.
For some of us this has been an issue since 4.10.0.123 was released last December, I see it mostly with OOT's hair, nice to see Daz finally acknowledging it, be even nicer if they would fix it.
