Fog & Clipping distortion

When I’m enabling fog, my polygons get distorted. The strange thing is only the polygons that are clipped have this problem!

Here’s a picture to explain it better:

I’ve tried different depth settings and glFog with GL_EXP and GL_EXP2. but this doesn’t help!

Is there someone who also had this problem?
