I'm having problems with the rendering of a WPF app over a remote desktop connection.

The applications chrome is rendering, but none of the content is coming through, as if the window is not drawing. Instead the previous content of the screen is showing in it's place.

This has been a problem with the application running on both Vista & Win 7, with remote control being taken from XP and Win7.

The problem is not application specific, if I create a new WPF app, with just a textblock on the window, it will also not run. (Neather will the windows preview in VS2008 display.)

Is there some trick to getting WPF running under RDP?

I read on Kevin Dente's blog (from a twitter post) that he was having trouble with WPF apps in virtual machines. While not the same as Remote Desktop, it's possible the problem could be the same. Kevin was able to fix his problem by disabling hardware accelleration by creating a DWORD registry value at

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics\DisableHWAcceleration

and then setting it to 1.

His original blog post is here: http://weblogs.asp.net/kdente/archive/2009/10/19/visual-studio-2010-beta-2-editor-performance-fix-running-on-a-virtual-machine.aspx

That may not be your exact solution, but maybe it points you in the right direction.
