It happened to me on Ubuntu. VLC and Jellyfin would both get screen tearing. Games were fine though. After some research, I found that turning on ‘force full composition pipeline’ in the Nvidia settings fixed it. Still too new to understand the how and why.
The author and a conservative source both overheard a confession from someone at a bar. That’s not really solid evidence in my opinion. They weren’t even willing to name the people who made the confession. Name them and force them to respond. Get some video from the conference proving they were in attendance. Do some kind of investigation. This just feels like half a story.
