@leocg And you think that it’s normal when Opera has a high CPU load, even if the video doesn’t slow down, not everyone has powerful CPUs i9, i7, i5, ryzen amd and only the browser is not always running, several more applications are running in parallel with the browser and they all slow down because I'm listening music or I’m watching watching videos, with another browser from Google Chrome, Vivaldi, Yandex Browse, Mozilla Firefox with the same CPU loads, the maximum load is 5% and minimum 2%.
