Hey guys it's probably not electricity.
I connected the monitor from the computer to my ancient laptop, found the same place in Yandex panoramas and here is the result. The first picture is from a computer, the second is from a laptop. The problem is clearly visible on the wires and steps. Moreover, when I zoom in and out on the first picture on my smartphone, this hellish mix of pixels appears. With the second, nothing of the kind happens. All the equipment was plugged into an outlet in one room, so no, the problem is not in the electricity.
