Defective Window Coating ?

Sounds like a case of a failed seal, especially if the streaking is between the panes.

Defective Window Coating ?

There's basically two types of low e coatings; a hard coat that is embedded in the glass, and a soft coat that is molecule thick layers applied on the surface of the glass. Soft coat low e is fragile, and when moisture enters the airspace the metals corrode creating spots and streaks that at first glance look almost like mildew.
It's broken and needs to be replaced.

It really doesn't matter whether its failed coating or moisture between the panes. The glass has failed and needs replacement. At least this type of failure is easier to spot!
