My muslim neighbour (F) takes sunbaths in the back garden without covering, is there a problem me seen her?

I am not a muslim and I live in a detached house but I can see my neighbours' backgarden, who are muslim, from my home office. I work from home most of the time, so, I spend a lot of time at my desk, which is near the window. One of my neighbours always wears a hijab on the street, but she often takes sunbaths without the hijab and wearing shorts. I was wondering if me seen her like this could be problematic (due to the contrast of clothes on the street vs. backgarden). I am not saying I am snooping, it is just that I am at the window working while she is at the backgarden enjoying the sun. Also, I am not the only neighbour in this situation as there are at least 8 neighbours who can see each other's backgardens, and many of us also use the backgarden to take sunbaths (but other neighbours are not muslim too).
