Glassy eyes, just a Linux issue?

Here I've gotten a good example of what I'm talking about. I can see that in the pre-rendered cutscenes and in some screenshots on here, Raz's eyes aren't supposed to look like they're made of glass, but instead should have a more natural gloss to them.

Is this just something with the (otherwise great) linux port, or what?
