About Virtualization, VDI, SBC, Application Compatibility and anything else I feel like
Within half an hour of writing the article "Application causes Screen Flickering in Citrix XenApp Session" I got a message that the hotfix in that article also fixes a similar problem in PowerPoint 2010.
Office 2010 uses hardware acceleration for displaying images and when this is enabled (which is the default) you will see constant screen flicker when you try to display a presentation with Images on Citrix XenApp (Server 2003):
The issue is fixed by installing the Hotfix mention in my previous article. As a workaround you can disable hardware acceleration in PowerPoint via File | Options | Advanced | Display | Disable hardware graphics acceleration:
Or via the registry: set the DWORD DisableHardware to 1 in HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Gfx
