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 Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
