If so, then this is a bug we've reported to Microsoft already and they are working on it.
How many displays in total are working? We've noticed you need 3+ for the issue to be obvious and that's why this is reported by DisplayLink users... because we make it easy to add that many displays on machines.

same exact issue here. if the dock is connected and you use any peripheral the process will spike just moving the mouse can be enough to get wudfhost.exe to spike up an extra 25% cpu load. (even though the mouse is plugged into the laptop)

with the dock not connected there are zero issues in fact the process doesn't even show in taskmgr

uninstall use the install cleaner tool, reboot reinstall no change.

Same here, build 1503 was fine with displaylink 7.7 m4 drivers, but as soon as I install 1607 I'm getting input lag, high CPU load from WUDFHost, and the screen fails to update until I interact with the window. Tried new 8.0 m3 drivers, uninstall/reinstall, old drivers, nothing seems to help. I'd rather not roll back to 1503 but it seems I may have to.

If anyone else find this thread they should give the 8.1 alpha driver a shot, its not perfect but it helps a lot. Made my win10 1607 setup usable again with two displaylink adapters connected.

close all apps, save work and prepare to reboot:

I have also tried the 8.1 alpha and this issue is still occurring.
From when I got the dock, I started with DisplayLink 8.0 M2, then M3, now 8.1.782 Alpha. Issue still occurring.
I've only ever had Win 10 1607 on this device, so not sure if performance is/was better prior to this version.

Windows 10 Pro 1607
Dell Inspiron 13 - 7000 series
Core i7-7500 @2.7 GHz
16GB RAM
Intel HD 620
Dell D3100 USB 3.0 Dock
1 external monitor connected at 4K via DisplayPort on dock.

Mouse cursor is laggy most of the time - especially once more than a few applications are open.
External monitor goes black for 2 seconds about every 15minutes during use, as though it is resetting itself. The laptop monitor remains on. There is nothing to indicate that the monitor is 'disconnected'... the primary screen settings remain in place.
WUDFHost.exe consumes 10-15% CPU continuously while the dock is connected and actions are occurring on the external monitor. When disconnected, this process is 0%.
Possibly related: audiodg.exe consumes 5-10% CPU continuously while the dock is connected.

Happy to provide more information if required.

Same issue here. It is impossible to use my ThinkPad USB 3 dock now because of the severe lag. It's been working fine for quite some time, but as of last week it's extremely laggy. I've been on Anniversary update for a couple of months, so it didn't happen along with the update.

Why so silent AlbanRampon and others at DisplayLink? Please try to advise here.
