This makes sports broadcasts very uncomfortable to look at. The issue appeared about 1-2 weeks ago, so it is very recent. It used to work fine on this HW for months, but not anymore. It does not depend on the browser, as the issue is the same on Firefox or Chrome. It does not depend on the DE, as KDE Neon suffers from the same issue. I had to install Windows 10, which of course is a tragedy. Posting this report from a 20.04.2 live USB session and the issue is reproduced with this as well.
