What’s new

High DPI support for multiple monitors

Citrix Workspace app for HTML5 supports DPI scaling for app and desktop sessions on single and multi-monitor sessions. This feature is mostly used with large-size and high‑resolution monitors to display applications, text, images, and other graphical elements in a size that can be viewed comfortably.

Note:

This feature is enabled by default for app and desktop sessions.

Benefits

This feature automatically adjusts virtual desktop and app sessions based on device DPI, ensuring content appears perfectly sized and sharp without blurriness. Apps and desktops are intelligently scaled based on monitor resolution and device pixel ratio for optimal readability and usability.

How to configure

• End users can disable this feature using session toolbar.
• Administrators can disable this feature using Configuration.js.

Session toolbar

In the Citrix Workspace app for HTML5 session, end users can disable this feature using the Toolbar > Preferences > Display Resolution > select Auto-fit screen option to disable the High DPI scaling.

Configuration.js

Administrators can disable using configuration.js.

Notes:

• Citrix recommends you back up the configuration.js file before making changes.
• Administrator-level credentials are required to edit the configuration.js file.
• The configuration.js file is located under the C:\Program Files\Citrix\Receiver StoreFront\HTML5Client folder.

To disable the feature, do the following:

1. Navigate to the configuration.js file.

2. Edit the file and set the scaleToDPI attribute to false.

   The following is an example of JSON data:

   {
     "features": {
         "graphics": {
             "dpiSetting": {
                 "scaleToDPI": false
             }
         }
     }
   }

Enhanced Alt+ key shortcuts support in double-hop RDP scenarios

Previously, Alt + key combinations such as Alt + Tab or Alt + F did not work properly in double-hop RDP sessions when using Scancode and Unicode mode.

With the 2509 version, Alt + key shortcut combinations now function correctly in double-hop scenarios, providing improved keyboard interaction for nested RDP connections.

Generic Client IME enhancement for Citrix Workspace app for HTML5 on Chromebook with multi monitors

Previously, enabling the multi-monitor configuration for the IME resulted in duplicate input on secondary displays in ChromeOS.

With the 2509 version, we now use the browser API to manage the relationship between key and input events, preventing duplicate characters from being entered per keystroke.

Configuration for blocking Global App Configuration service (GACS) requests

With the 2509 version, administrators can block Global App Configuration service (GACS) requests using configuration.js for on-prem stores. The attribute name is disableGACS. When you set this attribute to true, Citrix Workspace app doesn’t connect to any GACS endpoints.

Note:

The attribute disableGACS is set as false by default.

How to configure

Notes:

• Citrix recommends you back up the configuration.js file before making changes.
• Administrator-level credentials are required to edit the configuration.js file.
• The configuration.js file is located under the C:\Program Files\Citrix\Receiver StoreFront\HTML5Client folder.

To set disableGACS to true using configuration.js:

1. Navigate to the configuration.js file.

2. Add the disableGACS setting and set the disableGACS attribute to true.

   The following is an example of JSON data:

   {
     "thirdPartyServices": {
           "disableGACS": true
             }
   }

3. Save the changes.

Configuration for blocking feature flag requests

With the 2509 version, administrators can block feature flag requests using configuration.js for on-prem stores. The attribute name is disableFeatureFlag. When you set this attribute to true, Citrix Workspace app doesn’t connect to any feature flag endpoints.

Note:

The attribute disableFeatureFlag is set as false by default.

How to configure

Notes:

• Citrix recommends you back up the configuration.js file before making changes.
• Administrator-level credentials are required to edit the configuration.js file.
• The configuration.js file is located under the C:\Program Files\Citrix\Receiver StoreFront\HTML5Client folder.

To set disableFeatureFlag to true using configuration.js:

1. Navigate to the configuration.js file.

2. Add the disableFeatureFlag setting and set the disableFeatureFlag attribute to true.

   The following is an example of JSON data:

Enhanced session toolbar notch size

The 2509 version of Citrix Workspace app for HTML5 features a redesigned, smaller notch in the session window that you can drag and drop to any window edge. The notch design provides an optimal size, and the cursor pointer changes when you hover over it. This update addresses user feedback about wasted screen space and replaces the unclear orange indicator with a recognizable warning icon when Connection State Indicator (CSI) detects network issues.

Note:

When you use Citrix Workspace app for HTML5 version 2509 or later, this feature is automatically enabled for desktop sessions and requires no client-side configuration.
