Fix the problem where DisplayLinkUserAgent eats 38% of my CPU
OS is windows 10, DLUA is 7.9.6.30.0. This often gets in a state where the user agent sets there using between 35 and 38% of CPU.

7.9 M5 release for Windows is now available from our download area. Please create a support ticket for individual investigation if you meet any issue.

Mac on High Sierra 10.13.2 - DisplayLinkManager has been weighing on system even before the upgrade. Always hovers around 35% of CPU. Twice any other application. Often spikes to 50%.

WTF DisplayLink ... your crappy DisplayLinkManager software has been plaguing Mac CPU's for months, and you have no response? Get some courage - better yet, fix the problem

I'm having the same issue. Windows 7. Driver version 8.2.1646. Whenever I dare unplug my dock, the DisplayLinkUserAgent completely pegs a core. It makes my mouse freeze up, as others have stated, and my laptop becomes nearly unusable. I don't have admin rights on my work laptop, so I have to reboot and start up all of my apps again.

Windows 7 pro on a Lenovo T430 . Recently upgraded and got complaint about USB3 driver incompatibility. When watching YouTube CPU goes wild and DisplayLinkUserAgent generates 50K Page Faults per second. Constraining the processes to one core and running a simple CPU hog on the same core at a lower priority reduced CPU load to about 10%. Total memory usage stays under 100 MB.

We did notice here that if you move all your files from your desktop to elsewhere else, the CPU usage returns to normal... then, if you move back the files, it stills ok.
I hate IT

Seems to be related to what is actually being rendered. I only get massive CPUs spikes when watching videos.

Problem still present with newest driver version 8.4 (pre-production)
Problem with 100% CPU is absolutely clearly related to network DisplayLink. Plug in and have 100% CPU, disconnect and CPU goes back to normal. Need urgently a solution as otherwise no monitor is available. -

I had the same problem - stopped using my dock entirely. Today I installed the latest driver (December 1, 2017) from the link provided by Alban Rampon above and it worked. It is tagged as "Not for Production," so I was a little concerned. But so far, so good!

Same issue on High Sierra, it is brutally taking 98% of the CPU. Crazy.

Just noticed when connected to a usb-c dock with display link (on the latest driver 85514) on my mac book pro 15" 2,6 GHz Intel Core i7 it eats away 600% of processor resources when videoconferencing. 6/8 cores. That's some performance. We were about to order a few hundred docking stations for our meetingrooms. I ordered an investigation to see where to go now.

DisplayLinkMana uses 100% of a core on a Dell XPS 15 running ubununtu 16.04 with version 1.3.54

CPU hogging for MacOS/Sierra as well for me. taking between 12 and 30% of my CPU on i7/2.7GHz
This seems to be a new-ish problem for me in the past few weeks.

September 2017, still no fix for the high WUDFHost process load when using displays over DisplayLink. Video playback is choppy and the systes gets crippled from the CPU load.
Why isn't this fixed yet? This should be a priority
