Issue Description

Due to recent updates to Google Chrome 139 and Microsoft Edge 139, HTML5 video redirection functionality is impacted. When facing this issue, users cannot play the video and just see grayed out video content.

Versions Impacted

This issue occurs with a combination of following VDA operating systems, VDA versions and browser versions.

• Impacted VDA Operating Systems: More specifics will be added as identified

  • Windows 11 23H2, 24H2

  • Windows Server 2025

• Impacted VDA Versions:

  • All currently supported Citrix VDA versions. As of Aug 8, 2025 following are the versions which are still supported.

    • CVAD 2407, CVAD 2411, CVAD 2503
    • CVAD 2203 LTSR, CVAD 2402 LTSR

• Impacted Browser Versions:

  • Google Chrome version 139 and later.

  • Microsoft Edge version 139 and later.

Action Needed

This issue is fixed on VDA releases 2507, 2402 CU3 and 2203 CU7. On these versions, customers can use HTML5 video redirection with Microsoft Edge / Google Chrome 139. 

Note: In addition to the VDA upgrade, customers need to use the new HdxVideo.js that is packaged with the VDA releases mentioned above

Known limitations: At this time, there are a few known limitations with the fix

• When the Chrome window is squeezed, the HTML 5 redirected video goes out of the bounds
• With new HDXVideo.js, play/pause/sound buttons might not reflect the actual experience in some very specific scenarios.
• The volume slider is not shown if the video is in windowed mode.

In case, customers cannot upgrade to the VDAs in which the fix is available, Citrix recommends to stay on Microsoft Edge / Google Chrome 138 or earlier to ensure HTML5 video redirection is working properly

After updating Google Chrome or Microsoft Edge to version 139 (which are based off Chromium 139) on a Citrix VDA, HTML5 video redirection feature may stop working correctly.
