It’s a sharply defined intricate circular pattern about 15 cm across. A similar circle is next to it. You can’t see either until there is condensation on it. I’ve had the car for a year and never seen this. The marks are inside the window. If anyone wants a picture I’ll send it to you but it’s not easy to photo.

Moisture tends to condense first on pointy things which might be very small scratches, oil film, or even variations in crystal structures. Auto glass is specially made to break into small chunks instead of random splinters, so such a pattern would be expected occasionally, even without knowing exactly why.
IT doesn’t look random, it looks like a deliberate pattern. I though suction cup as it’s round but the internal parts of the pattern don’t fit this theory as I’ve never seen a suction cup that was patterned. It also looks too big, it’s a passenger door window and there are two of them so would be overkill for a suction cup. Very weird never seen anything like it before
