Hi freshcuruba,
Thank you for sharing the details of your setup. I found we should have a pair of such monitors in our lab, so we will definitely test this. For the analysis I would value if you shared more debug data. You can follow an instruction here ->
How to report macOS issues to DisplayLink to collect and send them to us.
Please make sure to describe in your report usual scenario after which the problem occurs and reference VIFR-6890 so we can connect your report for this thread.
Thank you and best regards
Szymon
