Fix "WindowServer [ERROR] - Unable to find display pipe for IOFB service: 18715" on MacOS

DisplayLink do not work properly with 4K screens @ MacOS 10.14. It looks laggy, jamming, like FPS drop.
I've described issue in details here: https://displaylink.org/forum/showthread.php?t=66349

        I should add: Late 2015 MBP w/ 16g of RAM. Issue occurs even immediately after restart, with no other applications running and no other noticeable noise in the logs.

        I do not have a 4k monitor, but I am having the same issue.

        System becomes laggy and unresponsive with displaylink monitor plugged in.

        After a hang, dozens to hundreds of messages are spammed to the logs that look something like:

        CoreDisplay
        [ERROR] - Unable to find display pipe for IOFB service: 12311

        I am running Mojave with the latest (5.0.1) display link driver installed.

        Thanks!
