I have been using Debian (Stable and Testing) for 3+ years now. Recently (about a month ago) I started having this odd behavior where all browsers use just one core (thread), and for some reason specifically number 7, and even resizing browser windows is super slow. Browsing/Scrolling is super slow. I have tried Firefox (70-71), latest Chromium, Brave, Opera. All act exactly the same. Just use thread/Core 7 and are super slow. Watching a video on YT or any animated content just kills PC performance. This was not the case at all until about a month ago.
Today I have reinstalled Debian Stable and I still have the same behavior.
