Weird spots on my windows - tint problem?
 

Today I noticed these weird spots on my windows. At first I thought they were spots where water drops dried up, but they aren't.

They seem to be inside the glass itself since I can't rub them off.

Has anyone seen this?

I'm wondering if it's a problem with my tint reacting with sunlight.

normal. "factory tint"

Can you feel them raised up at all? It might be bubbles in your tint. I've noticed in a few places on my back window that the tint seems to be bubbled every so slightly.

How long have you had the tint on the car?

Nope. Glass is smooth on both sides. It looks like water drops after they sit and dry. I even rubbed both sides of the glass with a napkin thinking it would wipe off, but no change.

It isn't really noticeable unless you look closely in direct sunlight. I just don't want it getting any worse.
