Has adhesive been pushed out between the window panes - defect?

So it's clear, two see nothing, one sees something. Not a defect, but hallucinations.

that's how I would put it.

when I stand in front of a window with a magnifying glass, I also see a lot...

the white edge on the glass? I wouldn't want that...

or is that taped from the outside?

I know what is meant. Basically, the seal between the panes protrudes slightly on one side. We also have that in 1/2 places. But it is hardly noticeable. Although I am extremely picky, I never thought of complaining about it.

Which white border? I only see the window frame.

Not the white edge. Sealant/adhesive protrudes between the panes.

Yes, in the lower third of the image between the two seals the glue just comes out, it’s hard to photograph because both seals are black and the glue is transparent...

But you can already see in the picture that it looks different between the seals
