This is clearly a breaking change, which has a fundamental impact at an architectural level. DisplayLink are not alone in their products no longer working:

In an email to Air Display users, Avatron wrote:

"We’re sorry to say that the Air Display Host software does not yet work on macOS 10.13.4. This new version of macOS has made some bold changes to its WindowServer and Metal frameworks, and unfortunately has broken the Air Display Host, as well as all of our competitors. The breakage is severe; it causes an inelegant system crash when you try to connect to any unaccelerated display or USB monitor. We have reported the bug to Apple and are hoping for a fix in macOS 10.13.5.

Until Apple issues a fix, we do not advise updating to macOS 10.13.4. Of course Air Display continues to work fine on 10.13.3."

Hopefully with enough pressure from the industry and the continued efforts of DisplayLink we will have a permanent solution.

Same over at Duet, they still recommend sticking to 13.3 for now.
"*We recommend staying on macOS 10.13.3*



Installing macOS release Version 10.13.4 will cause Duet Display stop functioning after the OS upgrade. We have alerted Apple to this issue and are working hard to find a resolution. These features continue to work as expected in 10.13.3.


We would strongly recommend contacting Apple though their bug reporting (https://developer.apple.com/bug-reporting/). It will help have the bug prioritized if Apple is aware how many people are affected by this issue.



We are actively looking into workarounds so that duet is not affected by the macOS bug, and will keep you informed. Please e-mail us if you have any questions. Thank you for using duet."
