Ubuntu 18.04 DisplayLink high cpu usage

I recently upgraded to Ubuntu 18.04 and now my multi-monitor setup with DisplayLink is no longer working properly.
CPU usage is almost at 100% all the time where DisplayLinkManager is using about 80% of it.
Did some one managed to setup DisplayLink on Ubuntu 18.04 and got it working smooth? I would love to play videos on the second screen like I could before.
I am using a Zenbook ux31a.

So there was a recent update of display link available that kinda fixed the problem for me. I still notice an exorbitant CPU usage at the beginning but after a fiew minutes 1-3 it getts a lot better. cpu raises if i do a lot with my mouse tough. I hope they will fix it soon.

I run mine on a Zenbook UX330ua running 18.04. Make sure you have the most recent drivers (https://www.displaylink.com/downloads/ubuntu). To be honest though, while the newest drivers do help decrease the CPU usage, it will still occasionally go really high and my computer will stop responding entirely.
If the computer still somewhat responds, you can kill displaylink and let it restart. I added this to my ~/.bashrc to do it in one command:
alias stopdisplaylink="sudo kill -9 $(ps -A | grep -i displaylink | awk '{print $1}')"
FWIW, DisplayLink also has some troubleshooting posts... but none of them have fixed my issues so far: https://support.displaylink.com/knowledgebase/topics/103927-troubleshooting-ubuntu
