Why are bg images on ios displayed at mega zoomed in size?

Question

css

Good evening!
Please tell me why the site images on the ios tablet are displayed on a huge scale? And only those images that go - bg

.div {
    background: url(img/moskow_sity_5.jpg)center center;
    background-repeat: no-repeat;
    background-size: cover;
    background-attachment: fixed;
    width: 100%;
    min-width: 320px;
    height: 100vh;
    padding-top: 0;
    padding-bottom: 0;
    border-top-width: 0;
    border-bottom-width: 0;
    border-style: none;
}

Those images that are inserted into html and have clearly fixed sizes are displayed correctly.
File - normalize.css, not included.
And what about iosa and background-attachment: fixed; something didn’t work - I already know, but it’s not about the lack of fixation, but the fact that the image is simply huge. (
Thank you!
