The hardware is Dell Latitude E5470 with Docking Station and monitor connected via DisplayPort (checked both ports and happens on both of them). Everything worked correctly on Ubuntu 16.04, but it happens on Ubuntu 16.10. Kernel 4.8.0-25-generic. The bug isn't related to cursor only, if focus changes by alt+tab it sometimes happens as well. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1553503 This is the same bug as this one, but closed. --- ApportVersion: 2.20.3-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/pcmC0D0p: vessel 5602 F...m pulseaudio /dev/snd/controlC0: vessel 5602 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 16.10 HibernationDevice: RESUME=UUID=56fab9c8-7226-47b9-91cb-a2c865f81bc0 InstallationDate: Installed on 2016-08-31 (47 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) MachineType: Dell Inc.
