VMware Horizon Client for Chrome 2209 | 20 OCT 2022

Check for additions and updates to these release notes.

What's New

Horizon Client for Chrome 2209 includes the following new features.

  • Support for ChromeOS Flex

    You can now use Horizon Client on devices running ChromeOS Flex.

  • Request/take screen control in Microsoft Teams

    With Media Optimization for Microsoft Teams, users can request/take control of screen sharing in VDI and RDSH desktop sessions.

  • Improvements to multiple-monitor mode

    When users connect or disconnect a monitor with the display setting configured to Use all displays or Use selected displays, the display changes take effect immediately, without requiring users to reconnect to the current session. This release also fixes certain display issues that previously occurred after closing the cover of the client Chromebook device.

  • Keyboard shortcut mappings

    Users can configure mappings that interpret certain keyboard combinations on the Chrome client system as Windows shortcuts in the remote desktop. This feature integrates the shortcuts associated with the Enable Windows key for Desktops option and Enable Alt-Backspace option, which have been removed from the client settings.

  • Support for multiple speakers

    If more than one speaker is connected to the client computer, and the remote desktop supports multiple device redirection with the speaker feature, you can use all the speakers connected to the client computer in the remote desktop.

For information about new remote desktop features, see the VMware Horizon 8 2209 Release Notes.


The user interface and documentation for Horizon Client for Chrome are available in English, Japanese, French, German, Simplified Chinese, Traditional Chinese, Korean, and Spanish.

Resolved Issues

There are no major bug fixes to report in this release.

Known Issues

Display and Multimedia

  • The Media Optimization for Microsoft Teams feature becomes unavailable after a network interruption occurs on the Horizon Client session.

    Workaround: For details, see VMware Knowledge Base (KB) article 85761.

  • After dragging certain apps to a small monitor, the app might have a strange boundary on Horizon Client for Chrome.

    This issue only appears when Chromebook has a very high DPI or an extended monitor has a small resolution. An example condition would be Chromebook with 4K(3840) screen in 213% DPI scale + small extended monitor(1920) in 100%. An example app could be a calculator that is not resizable.

    Workaround: You can make the following changes:

    • Enable High Resolution.

    • Change to a larger extended monitor. A 2560 screen will resolve the issue in most of cases.

    • For Chromebook, set the display scale to lower DPI (smaller font and icon).

  • H.264 decoding does not work in this release.

    The setting to enable H.264 decoding has been removed from the Horizon Client user interface.

    Workaround: None.

  • During a Teams audio call with the Media Optimization for Microsoft Teams feature enabled, no alert message appears when the user speaks with the microphone muted.

    Workaround: None.

  • When sharing the screen during a Teams video call with the Media Optimization for Microsoft Teams feature enabled, if the client user locks and then unlocks the Chrome OS, the screen share and outgoing video stop working.

    Workaround: None.

  • When the client user minimizes the remote desktop window during a Teams screen-sharing session with the Media Optimization for Microsoft Teams feature enabled, the screen-share contents turn black.

    Workaround: None.

Smart Card Authentication

  • You may see the following problems after authenticating with a smart card:

    • If you enter an incorrect PIN, log off from the server, and then immediately log in to the server again, you are prompted for Active Directory authentication.

    • If you log off from a session and then log in to the server again, the server fails to authenticate with smart card authentication.

    • If your published application session is idle and times out, and you unplug and then reinsert your smart card reader, you are not prompted for your PIN when you try to connect to a published application.

    Workaround: Log off or restart the Chromebook and log in with the smart card again.

  • If you enter an incorrect PIN during smart card authentication, Charismathics does not present any direct feedback in the dialog box.

    Workaround: This problem is a third-party issue. For more information, go to https://support.google.com/chrome/a/answer/7014689.
