In-session screen capture and window preview support for Browser Content Redirection
Browser Content Redirection now supports capturing redirected content using VDA-side screenshot tools, such as the Snipping Tool. Redirected content is also visible in taskbar previews and window switchers (Alt+Tab).
Chromium Embedded Framework (CEF) update
Browser Content Redirection now uses Chromium Embedded Framework (CEF) version 143, addressing security vulnerabilities—including CVE-2025-14174 (Stable Channel Update for Desktop)—and improving web standard compatibility.
Web page zoom synchronization for Browser Content Redirection
Browser Content Redirection now synchronizes zoom levels between the VDA browser and the client-rendered BCR overlay, ensuring consistent scaling of web content.
Enhanced window handling and thumbnail previews for Browser Content Redirection
Browser Content Redirection now provides a more integrated and native-like user experience. When you switch between applications using Alt+Tab or hover over the taskbar icon, you see a live thumbnail preview of the redirected browser tab. The feature also improves the handling of overlapping windows, ensuring that redirected content interacts seamlessly with other applications on the desktop.
In‑memory ICA File Handling
Citrix Workspace app processes ICA files in memory to enhance security. This approach prevents sensitive connection data from being written to disk. To maintain a consistent security posture, this behavior must apply uniformly across all supported launch mechanisms.
If you use SDK-based integrations, including ISV and healthcare deployments, the app also handles ICA files entirely in memory. In-memory ICA file handling across all launch scenarios supports security and compliance requirements. It delivers a consistent, secure experience regardless of the integration method.
Enhanced client-side touch keyboard
Starting with the 2603 version, Citrix Workspace app for Windows provides an enhanced client-side touch keyboard. This update improves consistency, performance, and reliability when you use on-screen keyboards.
Citrix Troubleshoot Connection – Recommendation Experience Updates
This release improves the Citrix Troubleshoot Connection (CSI) recommendation experience. The update enhances UI stability, clarifies network-related messaging, reduces non-actionable guidance, and expands administrative control.
Improved UI Stability and Clarity
The CSI layout now remains fixed and stable as recommendations update eliminating UI shifts that previously caused content to move up and down. The “View More” caret appears only when extra information is available, preventing misleading interactions when all content is already visible.
Clear Network Condition Messaging
CSI now displays short, user-friendly messages when network issues are detected:
- Low Bandwidth: Your internet is slow, making it longer to load Virtual Application or Desktops.
- High Latency: Your internet is experiencing delays, making Virtual Application or Desktops might load slowly.
- Weak Wi‑Fi Signal: Your Wi‑Fi signal is weak. If possible check your Wi‑Fi router is working properly.
These messages help users quickly understand potential causes of slow launches without IT assistance.
Administrative Control
Administrators can now disable CSI notifications for both Managed and Unmanaged Devices through GACS. This update enables centralized control that aligns with organizational policies.
Anti-DLL Injection Event Logging
Starting with version 26.3.0, Anti-DLL Injection no longer displays notifications to end users, eliminating confusion during virtual app and desktop sessions. If any untrusted module load is detected, it is silently logged into Windows Event Viewer and reported to Citrix Director and Monitor with detailed metadata, such as the path and target process. This gives administrators clear, actionable insights to guide users in removing risky applications from their endpoints.
Fixed issues in 2603
- The HDX WebRTC Media Engine (HdxRtcEngine.exe), which supports Microsoft Teams and UCSDK optimization, might exit unexpectedly on endpoints running non-English operating systems. This issue occurs when system hardware descriptions contain Unicode characters. [CVADHELP-30545]
- When you redirect URLs from the VDA to the client using bi-directional content redirection, the local browser window might open behind the Desktop Viewer window. This issue occurs if the desktop session runs in full-screen mode. [CVADHELP-30546]
- When redirecting URLs from the client to the VDA using Bi-directional content redirection, the desktop session might launch successfully, but the browser fails to open the redirected URL. [HDX-94125]
Known issues in 2603
- Copy and paste from the client to the VDA works consistently. Copy and paste from the VDA to the client might stop shortly after the session reconnects. [CVADHELP-30717]
