Hi 3ventic, thanks for interesting with my problem. Here you have gif with completely clear installation of chrome and Task Manager details. I have i7 CPU so I don’t think it’s CPU problem, generally I can have even three or more streams played and everything works great, but when I embed chat, probably its some js/css is broking something.
Here is GIF: DETAILED GIF
EDIT: I have found that deleting application.css from iframe in dev tools fixes problem, but it is very hard to find what is wrong in so big css
