Also reporting an issue after upgrading to 14.2. Rolling back to 14.0 resolved things.

I observed similar symptoms - high CPU usage by DisplayLink, lagging on the external monitors but not on the laptop screen.

Configuration:
- Wavlink WL-UG69PD5
- LG HDR4K and LU28R55 both running at 4K scaled down to FHD by the OS
- 13-inch M1 Macbook Pro
- MacOS Sequoia 15.7.2

As mentioned earlier in this thread, If the original manufacturer of your DisplayLink-based product has been unable to assist you then I would suggest reporting the issue to DisplayLink directly by following the process outlined here --> https://support.displaylink.com/know...to-displaylink

I add to the club. I was about to buy new macbook till I found this problem. I am using an AIR M3 with the following :

- 2x DISPLAY 1600p via HDMI
- Baseus Spacemate 11 in 1

I have a little different behaviour.

OSX 26.2

version 15.0 : Unusable, CPU > 100%
version 13.1 : Usable but CPU > 50%
version 14.x : CPU above 60%

Upgrading to OSX 26.3 was a major improvement that bringed the following :

version 13.1 - 14.0 : CPU mostly under 20%. Some spikes up to 50% but no lag at all.
version 14.x : Again with cpu above 60%. Little lag
version 15.0 : CPU > 100%


UPDATE 20/02 : I wish to add that my memory tab after a few days shows a wopping 7,5Gb of use. Closing the Displaylink Manager and restarting it goes back to normal amount ( 300mb-1Gb ). I do not know if this is a display bug or real. can anyone confirm this?

Hope this will be interesting for DisplayLink guys.
