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

    Same here.

    Macbook Pro Mid 2014
    OS X: 10.14.4
    The dock is a Targus Universal DV4K
    Display Link driver: 5.1.1

    I have the same issue, found the same error log in console.app.

    I'm using lenovo dock 40AF0135CN, Macbook Pro 13" (2018), connecting a 4K monitor.
    It's laggy and having FPS drop when using resolution "1920 x 1080" (which displays in retina mode).

    I have to workaround by using 1080p (which displays in 2K mode, blurry and wasted my 4K monitor) but at least it allows me to continue using it.

    Hope the next update on the driver will address this issue.

    Same issue with my Macbook Pro 15", running driver 5.1.32 and Mojave 10.14.3.

    My dock is WL-UG69PD1.

    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:

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

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