Fix DisplayLinkUserAgent using over 4.5GB (~30%) of memory on Mac
macOS Mojave 10.14.5
16 GB 2133 MHz LPDDR3
This is addressed moving forward via the macOS app with features being added currently.
The macOS app (1.x+) is replacing the classic driver with kernel extensions (5.×.x).

Any updates on the issue? Still having it in 2021..
8.50 GB after two weeks
MacBookPro, 8GB RAM, 10.14.6. Looking in Activity Monitor after several days of work (without rebooting), DLUA sits at 2.66GB memory usage from just 3 threads—by far the most of anything running on my machine. After reboot, it comes back up as using 5.3MB (no, that's not a typo).
I am running the latest available DL driver (5.2.1), and have verified that the kext is enabled.

Displaylink agent 5.2 consumes 2GB + and up to 4.5GB for me.

I am having the same problem- I have to force close the DisplayLinkUserAgent app every day or two or it slowly consumes more and more. I've seen it grow as large as 8GB before, though I usually catch it before then.
Mac OS X 10.14.6
30GB RAM (2x16GB DDR4@2400 MHz)
Also running version 5.2 of the Display Link software (the latest version available as of this writing)
Same thing for me, it arrived at 2GB of memory in 10 days of uptime (but most of it show up as "compressed").
