Playback is jerky when other programs are running. The system is underutilized and has more than enough capacity.
I do not have similar problems on other systems like Linux Mint, iOS 10, Android 9.
My Windows PC is the most powerful system I have, so I'm particularly surprised here. The error can be reproduced at any time. If you want I can t.ake screenshots or videos and also send you performance data of my system.
