NO I have seen that problem you probably lost you UV mapping when you added the clip map. This is a bug, but you can correct it easily.
Just go to window and set again the UV or mapping coordintes.

thx for hint

I checked - all projections are UV and the scale is always the same

so the problem is somewhere else :?

What if you render with greater resolution - slow but that fixed one moire problem I did had.

It's an render's resolution issue and it's common - if one tried to render such shader the way that the smallest sinlge hole in the metal was larger than a pixel, the problem would dissapear.

In Your picture You can't really single out a single hole, so using such a shader in this very example is piontless for me. Semi transparent colored plane would work better, and You'll get rid of undesired effect.
