Shaky YouTube videos

A while ago, I posted here about some YouTube videos that were shaky.  I soon discovered they were shaky in Firefox, wouldn't play at all in Chromium and played smoothly on Edge.  This was on a Gigabyte mom board and I was able to resolve the problem by installing Pacman.  I have since moved on to a refurb Dell 7060 and the problem is back.  However, this time, Pacman killed the video entirely and it took me a lot of effort to get it back.  Is there some YouTube format that's causing this problem?  It only happens on some videos and most play fine. Here is one example https://www.youtube.com/watch?v=cueTzJAW1kU&t=196s I'm running openSUSE 15.6 & KDE. tnx jk
