Fix for Citrix issues with application freezes and crashes in recent versions of Citrix Receiver

If users are experiencing random crashing and or freezing with Citrix hosted applications when using RemoteScan, and have they have version 4.9, 4.10 or 4.11. of Citrix Receiver installed, you may need to disable Hardware Acceleration on the workstation.

This is a known issue with some versions of Citrix Receiver as listed above, however looks to be fixed in version 4.12.

To fix this issue, do one of the following two actions:
1.    Disable the Citrix Policy “Hardware Acceleration for Graphics”.  
2.    Alternatively,  edit a registry setting on the workstation called UseD3DHybrid making the value 0 at one of the following locations:

32-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\GfxRender
 
64-bit systems: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\ GfxRender

After editing the registry log out of the scanning application and Citrix Receiver completely then log back in.

  • UPDATE:

    If users are experiencing random crashing and/or freezing with Citrix hosted applications when using RemoteScan and they have versions 4.9 - 4.12 of Citrix Receiver installed, they may need to disable Hardware Acceleration for Graphics on the workstation.

    This is a known issue with some versions of Citrix Receiver, however looks to be fixed in versions released after 4.12.

    On the workstation, go to Local Group Policy Editor, then Administrative Templates, Citrix Components, Citrix Receiver then User Experience.  Disable the Hardware Acceleration for Graphics Setting.

    If this setting is not found in the Local Group Policy Editor or you have more questions in regards to this please contact your Citrix Technical Support team.
