Mojave kernel_task high increase over time

So its been 4 weeks since I posted originally. Over this time I've actually used displaylink drivers 3 days a week and during this time on Mojave 14.1 the kernel task cpu utilisation has increased from 2% to 20% on average. Today I tried reseting the SMC and PRAM but this made no difference. If I uninstall Displaylink kernel task utilisation returns to 1 or 2%. Reinstall Displaylink and it raised to 6-8%. So I guess this is the sequence every 4 weeks....uninstall and reinstall to reduce the load on the MAC. I know when its had it as the fan comes on a lot more than it should.
