High CPU usage with latest driver

I also have this issue.
Xubuntu 18.04
Kernel Version: 5.3.0-26-generic
DisplayLink Version: 5.2.14
I use an NVIDIA GT 650M with nouveau

Processor load of DisplayLinkManager process (with one 2560x1440 60Hz monitor connected) reaches 14% to 40%, when moving mouse it reaches around 200% in sum. Load is similarly disastrous when watching videos. I used htop to look at load. I have 2 cores and 4 threads so this impacts cpu performance immensely!

Is this supposed to be normal behavior or can we expect a fix?
