Web session mouse input tracks incorrectly after display change

Hello, all! I've noticed an inconvenient issue that may or may not be a bug.

Expected Behavior

Mouse movement and input is tracked normally inside web sessions, allowing you to accurately click and interact with content inside the web session, even after a display change has occurred on the device running RDM.

Actual Behavior

Mouse movement is tracked incorrectly and input does not work after a display change as occurred on the device running RDM.

First Recognized Occurrence

This issue appears to have existed as long as our company has been using RDM, which goes back to at least 2022.x.x.

I can currently reproduce the issue in my environment:

Software

• Remote Desktop Manager 2023.2.32.0 (64-bit)

• Windows 11 23H2 Build 22631.2506

Hardware

• 1 qty. Microsoft Surface Laptop Studio

  • Inbuilt Intel Iris Xe Graphics

  • Inbuilt LQ144P1JX01 display 2400x1600 @ 120 Hz

• 1 qty. Dell P2722HE, D6500 monitor with inbuilt USB-C dock - 1920x1080 @ 60 Hz

• 1 qty. Dell P2722H monitor - 1920x1080 @ 60 Hz

Steps to Reproduce

1. Laptop is standalone without additional monitors, RDM web sessions work as expected

2. Connect laptop via USB-C to dock which adds two additional monitors

Troubleshooting

I've tested and this appears to happen only in this direction. If you have RDM open and disconnect your laptop from a dock, web sessions appear to track mouse movement and input correctly.

Additionally, I tested this with a slightly different hardware setup and was able to replicate the issue the same using:

• Same laptop

• Anker PowerExpand A8394 USB-C dock

• 2 qty. MSI G2712 at 1920x1080 @ 144 Hz

I had hoped that simply closing the session and re-opening it would resolve the issue, however it does not.

Workaround

In the meantime, closing RDM entirely and re-opening it appears to resolve the issue.

If this is indeed some kind of bug, I hope that some of the above information is helpful. If not a bug and this is expected behavior, I will pass that information along to our team. Thanks!
