My latest email to Kate:
And for my Ubuntu 20.04 computer, which has the same problem on the adapter, see this post: #20 (comment)
And my zip file for it is attached: "DLSupportTool_Output_2023-10-06T17:01:06.165973 [Ubuntu 20.04].zip"
I've also attached an extra zip file on this same computer where the issue is NOT present, in a different monitor configuration: "DLSupportTool_Output_2023-10-06T16:17:47.774128 [issue NOT present].zip"

My email describing this:
Kate, my replies:
And just to be sure, if you only have two monitors connected to the Club 3D adapter everything is okay but as soon as you add a 3rd monitor (the one connected directly to the computer) the issue starts?
No, sometimes it happens with only 2 monitors plugged in.
Would you be able to check this problem with directly connected displays (on desktop PC with larger number of outputs)?
I don't have a desktop PC (I haven't since 2003), but to answer the question: with directly-connected displays, rather than going through the Club3D adapter, the problem is not present. The problem is only present with the Club3D adapter in use. Here's a scenario: #20 (comment)
Another diagnostics file for this scenario is attached.
Thanks!

To clarify for the setup just above: when I remove the Club3D adapter entirely, and direct-connect the 4k monitor via a DP to USB-C adapter, and direct-connect the 2k monitor via a USB-C cable straight from the monitor, I do not get the above aberrant behavior where the mouse can go off-screen.
I can also direct connect the 2k monitor via an HDMI cable to an HDMI to USB-C adapter, and again, I do not get the aberrant behavior. I only Get it when using the Club3D adapter.
Here is the setup that does not have the problem:
- laptop 1920x1200 59.95 Hz
- 2k 2560x1440 59.95 Hz connected straight to laptop via USB-C cable
- 4k 3840x2160 60.00 Hz connected to laptop via DP to USB-C adapter
Here is the other setup that does not have the aberrant behavior:
- laptop 1920x1200 59.95 Hz
- 4k 3840x2160 60.00 Hz connected to laptop via DP to USB-C adapter
- 2k 2560x1440 59.95 Hz connected to laptop via HDMI to USB-C adapter
The mouse-going-offscreen aberrant behavior is only present when using the Club3D adapter, and even then, only in certain configurations as described above.
from bug_reports.
Here, with only monitor 2 in this image being connected through the Club3D adapter, and all other monitors being connected through USB-C interfaces or adapters, the aberrant behavior is also not present! It's working fine in this setup:
