Omnissa Horizon Client Next Release Notes

This Tech Preview of Horizon Client Next is available for early testing before its official release.
Tech Previews are not intended for production environments.

Horizon Client Next features a new, modern interface design for Horizon Client across Windows, Mac and Linux platforms.

Why the new interface?

For end users: The previous Horizon Client had three different interfaces, that is, one for each platform. That meant users working across multiple devices had to relearn where features were located and how settings worked. Horizon Client Next eliminates this friction, letting you focus on your work instead of hunting for options.

For IT administrators: Managing three different client experiences meant three sets of documentation, three training programs and inconsistent user support issues across platforms. A unified interface reduces training costs, simplifies troubleshooting and makes it easier to roll out new features consistently.

2606 - Known issues and features under development

Display and Monitor

• Windowed mode scaling may not apply dynamically. Workaround: Set the desired resolution before launch.

• Selecting the display after launching the Published Application will not move the Application to the selected monitor Workaround: Set the display monitor for Application before launch of the Application and avoid changing the display monitor.

• Resolution and Scaling options are not available when the user selects any of the full-screen options. Workaround: This option is available only when the user selects custom display options

Performance

• No performance limitation.

Authentication

• Launching Workspace ONE is not supported.
  Workaround: On Windows, rename the Client Next executable file to horizon-client to use Workspace ONE Mode.

Platform-Specific Issues

Windows

Performance

• High session counts (~60 sessions) may increase login/launch times and memory usage, cause rendering issues, or make the application unresponsive.
  Workaround: Limit concurrent sessions and monitor system resources. If the application is unresponsive, you can force quit the app and relaunch it.

• The TechPreview app may consume high CPU/memory.
  Workaround: Close unused applications and monitor resource usage.

Authentication

• Launching Workspace ONE is not supported.
  Workaround: On Windows, rename the Client Next executable file to horizon-client to use Workspace ONE Mode.

• FIDO2 authentication is not available.
  Workaround: Use other supported authentication methods.
