Screen Flicker in AutoCAD on Xenapp 4.5 or 5.0 on Windows Server 2003
Issue
The screen flickers or flashes black rectangular areas for the Ribbon, Toolbars, or dialog boxes.
Solution
AutoCAD uses the Windows Presentation Foundation (WPF) for many of the user interface components. There is a patch from Microsoft for WPF that fixes this flickering issue with Terminal Services:
