I can compare this by changing refresh rate and by connecting one of displays directly to the Mac.
Display connected directly to the Mac runs well with all refresh rates above 60Hz and the change is perciptible.
When I connect this dock with displays attached to the windows machine both displays' refresh rate feels correct and refresh rate change is perceptible.
Displays show that display is using 144Hz in both cases (in-display menu).
I suspect it may be due to screen recording in 60FPS, but I may be wrong.
This is for sure a bug in MacOS DisplayLink Manager. I'm using 1.8.1 version.
I also saw reddit thread where more people had similar problem with other displays, but I can't find it now.

Lenovo's support page for the dock you are using -->
https://support.lenovo.com/us/en/sol...-service-parts has a link to the manual for the dock -->
https://download.lenovo.com/consumer...1.0_201802.pdf
Electronic pages 13 and 14 of the manual list the supported resolutions and refresh rates. The maximum refresh rate supported for resolutions over 1920x1080 is 60Hz.
