Problem description:

I have a hybrid WinForms/WPF (so I'm not sure if its a WinForms or WPF issue) application with an ElementHost. The child element is a WPF UserControl with a TabControl. Via the ItemsSource different types of tabs are displayed.

1. WinForms Controls, integrated via a WindowsFormsHost
2. WPF Controls, directly through the ElementHost
3. WPF Control, provided via a WinForms UserControl, hosted on a WindowsFormsHost, which displays a WPF Control via an ElementHost

The third case seems pretty crazy and stupid, but is the case.
Switching between the tabs, the application crashes pretty fast with 2 exceptions.

1st UCEERR_RENDERTHREADFAILURE System.Windows.Media.Composition.DUCE+Channel.SyncFlush
2nd FATAL_USER_CALLBACK_EXCEPTION An unhandled exception was encountered during a user callback.

Expected behavior:
The render thread failure is not random and always renders on the correct thread.

The stack trace is all WPF, so transferring there until it can be established the issue is in our code.
