New Fixes in This Release

1. When moving the mouse cursor over the toolbox bar and drawing area of a third-party CAD application in which the desktops are HDX 3D Pro-enabled and running Windows with Simplified Chinese, the mouse cursor might disappear.

   [From ICAWS750WX86034][#LC1321]

2. After disconnecting the Receiver session, reconnecting to a locked VDA session can fail on a computer with HDX 3D Pro with NVIDIA graphics card.

   [From ICAWS750WX86034][#LC1629]

3. The mouse pointer might not assume the proper shape when the mouse is positioned at the edge of a Microsoft Notepad application window.

   To enable this fix, you must set the following registry key:

   • On 32-bit Windows:
     HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\HDX3D
     Name: EnableUnknownCursorHandling
     Type: REG_DWORD
     Value: 1
   • On 64-bit Windows:
     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\HDX3D
     Name: EnableUnknownCursorHandling
     Type: REG_DWORD
     Value: 1

   [From ICAWS750WX86034][#LC4160]

Fixes from Replaced Hotfixes

1. When users load a customized cursor in a HDX 3D Pro desktop, the correct cursor color does not appear.

   [From ICAWS750WX86021][#LC0917]

2. The VDA might become unresponsive if a VDA session is maximized when using graphic applications.

   [From ICAWS750WX86030][#LC0908]

3. This enhancement provides additional compatibility with Nvidia’s GRID API related to GPU pass-through and vGPU use cases.

   [From XD710ICAWSWX86004][#LA5251]

4. This enhancement provides additional compatibility with Nvidia's GRID API related to GPU pass-through and vGPU use cases. Specifically, it addresses the following issues:

   • With GPU pass-through enabled, sessions with certain custom resolutions fail to launch.
   • In full-screen VDA sessions with a 2560x1600 custom resolution, switching among open applications and/or closing applications fails to refresh the session window. As a result, a ghost window remains on the screen.
