Awaiting future updates!

Try uninstalling the drivers, reboot, and reinstall and reboot. I've noticed, like a few others, that displaylink drivers over a period of time result in kernel_task CPU utilisation increasing. This may be the result of the lag. I now routinely watch my kernel task utilisation and once it gets to averaging about 20% i repeat uninstall and reinstall to get it to return to about 2%.
