A change in Prism textures?

I noticed that some time this week, there was a change in how Prisms are textured. I don't know if this is intentional or not, or just a problem with how the system culls details. Zoomed out, an old prism texture looks fine, but if you zoom it, it gets all twisted.

Is this supposed to be happening, or is this some bug with the latest update? The only reason I ask is because I made the textures for an aircraft that uses prisms a while back and now the aircraft is a texture grid nightmare. Oh, and I'll post some picies just to show off what I'm talking about. (Uh, can't upload the texture, I'll make links instead.)

Oh, and, if this is supposed to happen, uh, can we go back to the old way it got textured? Please?

Hi Jillian and Salen, I saw the thread you mentioned and've got it bookmarked. I'm going to ask our graphics gurus about this. In the meantime, please send me any examples which visibly demonstrate this--as well as earlier photos of how it's *supposed* to look if you've got them. Thanx!
