Do you have a light tint? Maybe it has cracked/crazed.
Are you sure it's inside? Maybe it is scratches in the glass. Can you feel the marks? Hag you tried wiping them? Windex? If it is inside and yo can feel it but you can't wipe it off with a mild cleaner, do NOT try and scrape it with anything. You will damage the defrost elements if you do |

Oh that's so neat, it looks like a sheet of continuous crystallized ice formed then cracked across various grains. Seems unlikely, though. Seems more likely they're micro-scratches that form nucleation sites for ice crystals, but then long straight runs of them would also be very surprising.

Looks like the window lamination (either factory or tint) has a few few small ridges folds, or (more likely) cracks in it that allows condensation through to form those ice crystals. Really cool.
