DisplayLink Software - High CPU on MBA

I have looked at Activity Monitor to see that, in this order, the following are consuming CPU:
a. WindowServer (insanely active)
b. DisplayLinkManager (insanely active)
c. Screen Sharing (insanely active)
d. kernel_task
e. DisplayLinkUserAgent (not very busy)

I'm running DisplayLink version 5.2 under Mojave 10.14.6 on the 2017 13'' MacBook Pro and I'm experiencing the exact same issues under the same circumstances.
