End user might experience a delay and the origin of the zoom can move at random when zooming in and out of some CAD applications using the mouse wheel.

To enable the fix, set the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA

Name: DisableAppendMouse

Type: DWORD

Data: 00000001

However, when you use the HDX session after setting the registry key, certain features that programmatically set the mouse pointer location might not work as expected. The features are:

• Mouse Snap To feature.
• The capability to synchronize mouse location between users with GotoMeeting screen sharing.
• The capability to synchronize mouse location between users with Skype for Business screen sharing.

Problem Cause

Citrix graphics driver receives an incorrect mouse location from the operating system.
