Omnissa Horizon Client grey screen - MacBook 2024 models

[KvackEvolution]

Hi!


When I updated to Mac OS Tahoe 26.0 (25A354) on my MacBook Air 2024 running latest DisplayLink Manager 13.1 (build 46) and are trying to connect to my Windows 11 VDI machine through Omnissa Horizon Client the VDI session Window (See picture attached) grays out. But if I connect through web browser to the VDI desktop it works. Or if I disconnect the dock and run it on the internal Macbook display the grey block disappear and the desktop behind it becomes visible.

What I have tried:

- Restart master VDI image and Mac
- Two different models of Targus 60W USB-C DisplayLink Dock 180 and Dock 182.
- Downgrading Omnissa Horizon Client App to "VMware-Horizon-Client-2312.1-8.12.1-23531248"
- Tested different VMWare Blast display settings in the Horizon application on the client side. Across different versions.
- Tested different 2024 models of MacBook computer (Air and Pro), Mac OS Sequoia (Works everytime running version 13.1 of Manager) and Tahoe 26 (Doesnt work, no matter Air or Pro running 13.1 of manager).
- Tried registry key "PixelProviderForceViddCapture" workaround from https://community.omnissa.com/forums...-blank-screen/.
- Downgrading DisplayLink from version 13.1 to version 9.0.

What is wierd also as the picture attached shows is that if you mouse drag in the corner of the grey window a part of the VDI desktop becomes visible behind, but returns grey if you release.


Also sent a ticket to the DisplayLink Support through email.

If anyone has any ideas or suggestions of what more to check. Please let me know!

Best Regards

EDIT: Tried updating to DisplayLink Manager version 14.0 released for Tahoe. But the problem still exists in this version.
