I do not appear to have anything intermediate on my system. I also noted that under Wayland the neither the separate cursor for the tablet or the mouse cursor shows lag in the newer kernel. Unfortunately, I have no other clue as to what is going on. The system report will show Linux ubuntu 5.4.0-1022-raspi as I have rolled back to that to avoid the problem for now. ubuntu 20.04.1 LTS ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-1022-raspi 5.4.0-1022.25 ProcVersionSignature: Ubuntu 5.4.0-1022.25-raspi 5.4.65 Uname: Linux 5.4.0-1022-raspi aarch64 ApportVersion: 2.20.11-0ubuntu27.13 Architecture: arm64 CasperMD5CheckResult: skip CurrentDesktop: LXQt Date: Sat Dec 12 16:27:02 2020 ImageMediaBuild: 20200731 SourcePackage: linux-raspi UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1907922/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
