XenApp 6.5 – PowerPoint 2010 flickering

I noticed my screen will flicker from time to time while working with PowerPoint via XenApp 6.5.  Although no one was complaining about it, it really began to annoy me and figure I look into it.

I found out that Office 2010 utilizes hardware acceleration for displaying images (enabled by default), from time to time you will see constant screen flickering when you try to display a presentation with images via XenApp 6.5.  I remember back in my XenApp 5.0 days this really occurred a lot with PowerPoint 2010 as that environment lived on a Server 2003 infrastructure.

The fix:

For Windows 2003,  the issue is fixed by installing this Microsoft Hotfix.

For Windows 2008, you can disable hardware acceleration in PowerPoint via File, Options, Advanced, Display, then click Disable hardware graphics acceleration for each user…

Since most of us XenApp folks are all about automating user profiles, you can set the following regkey into your mandatory profile, or hive it in via a GPO, or AppSense, Citrix Profile Manager, or however you manage your profiles.

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Gfx]
“DisableHardware”=dword:00000001
