Question DisplayLinkUserAgent 10.14.5 clamshell mode memory leak

Hi guys, I have quite a problem with memory leak.
DisplayLinkUserAgent uses just too much RAM over short period of time. And not only that
As I am currently using clamshell mode, I have to switch between extended and mirrored display quite often (after restart, or after quitting program that is using GPU, otherwise it just lags and has severe glitches)
Probably that is triggering also this memory leak, after just 5 days of not restarting, just going into sleep mode, that process had almost 5GB of RAM used, from 5MB after fresh boot (currently, uptime around 10 minutes, using 14MB)

Do you have similar issues with this process? Is there any solution or workaround? Can I kill it and restart it somehow without needing to restart whole computer?

Unhappy Memory leak in DisplayLinkUserAgent

Same here. It is eating almost 4GB of memory.
Uptime is 3days and 7hours.

Environment: MacBook Pro 15-inch, 2016, macOS 10.14.6, DisplayLink driver 5.2.1Beta2.

Kind regards,

I "like" to see that they still did not fix it, even though, when I wrote the issue to support, the answer was:
"We're aware of this bug and are looking to resolve it in the next release."

But as a quick workaround, this time nothing broke when I just killed the process, it started on its own again and no glitches so far.
If something will happen, you can just disable and re-enable screen mirroring (or enable and disable, depends on your use) and GPU should fix itself
