• The non-administrator user account cannot access the %WINDIR%\System32 folder
• When the non-administrator account tries to access this folder, the WPF caching code is triggered, causing the flicker

• See Microsoft KB: Your screen flickers when you start WPF applications in a Windows Server 2003 terminal server session
