Certainteed Windows

We just bought a nine year old home with Certainteed vinyl windows. We are just now noticing that in between the double panes there are small silver dots. The dots we are assuming are a coating. The dots are heavy in the bottom corners but about an inch away from the frame. In the bottom corners the dots are numerous enough to be solid.
What is causing this? Would the window warranty cover it?
