Public bug reported:
Something has regressed recently to cause stuttering video playback.
especially at the Cmore.fi. 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.
