RDS client single mouse clicks produce double clicks for just one user

Question

Greetings,

I have a single Windows 10 user that connects to an application server through RDS and when he interacts with the application it's producing double clicks when single clicking. Using TeamViewer, I connected to his computer remotely, rebooted, logged into the computer using my creds (first time), he logged into the RDS session as himself and was able to recreate the issue. His computer was Windows 10 v2004

I completely reset his Windows 10 computer and fully patched it and it happened again on the first try.

Had him connect to another computer through RDP and he was able to reproduce the issue but with far less frequency. he is currently working in this manner. Less then ideal.

He is running Windows 10 v20H2

RDS is running on Windows 2019 Datacenter

Application is on Windows Server 2016 Datacenter

All platforms are up to date on their Windows updates.

NO OTHER USERS ARE EXPERIENCING THIS ISSUE.

I feel that it's not Windows 10 or the users profile on the client. Where I'm a little unsure with is could it be a profile issue on the application server? If I remove the users windows profile on the application server could that resolve a mouse click issue????

Thanks ahead of time for your assistance.

I've had a similar issue, things appear to randomly double click. Most strangely, right clicking sometimes appears to trigger a double left click (I think it might be a right click followed by a phantom left click).
Often Ctrl+V will paste more than once.
Sometimes keystrokes seem to be out of order (arrows and letters and pasting). There is nothing quite as mind bending as typing, pressing an arrow key and pasting and having your paste end up in the middle of what you typed.

I can't be sure exactly when it started, but for me it was around the release of windows 2004. My destination was updated to 2004 and the client was updated to 1909 at about the same time. Its persisted with the destination updated to 20H2 and I've tried updating my RDP client to 1.2.1755 but the issue persists.

I'm running it as a remote app, I tried various settings in the RDP file. I even disabled UDP thinking packets were getting reordered. Latency is typically around 30ms but I wonder if this issue is related to lag spikes / jitter or something.
