Thanks @vanvugt, I had to wipe the setup and replace with Windows to quickly work around from the issue. However:
- Wayland vs. X11 makes no difference. I usually prefer Wayland, but tried X too. Also, KDE Neon uses X as default. - I investigated a bit further, and indeed the time-line of the issue matches quite accurately with the kernel 5.8 upgrade. Also, the KDE Neon installation media comes with 5.8 currently. Since I can now only debug with live media, I guess I need to try 20.04 vs 20.04.2, unless someone else is able to repro this. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1914877 Title: Stuttering video playback To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1914877/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
