What's with the background bug in chrome on ipad?

Question

css

Hello.
tocode.ru/landing/index.html
For the first time I encounter this, on the ipad it is in chrome in some sections that the background is not displayed. Open first in safari and understand where the background should be. The most interesting thing is that the background only works in sections 1 and 6, although the code for all sections is the same.

.plx-1 { 
  background: url(../img/bg-plx/s1-plx.png) no-repeat fixed 50% 0 / cover;
  padding-top: 45px;
  padding-bottom: 93px;
  .advant {
    padding-top: 95px;
    margin-left: 215px;
  }
  .arg {
    span {
      font-size: 86px;
    }
  }
  .txt {
    padding-top: 60px;
    padding-bottom: 100px;
  }
}

Who faced how to solve the problem? I don't know what to think anymore. The problem with debugging is that I can't even emulate this behavior. In the chrome inspector (on the desktop) in the ipad emulation, everything works as it should.
Maybe you can somehow emulate the chrome ipad in the inspector?

I went to your page from the iPad through Chrome and Safari, all the backgrounds are displayed, but the map is not loaded in Chrome, only the point is and the fixed menu (its position) works every other time, it is, then it is not.
