Hello, the problem is on the site http://vk.com/
when scrolling up / down it shows a lot of advertising blocks, but there is no advertising there I think this is some kind of error in the adblock extension for google chrome I scrolled on other browsers and there is no such problem on this site, and on another device with google chrome and with windows 10 the same problem on the site http://vk.com/
my devices on windows 10 with google chrome
