: 'UCEERR_RENDERTHREADFAILURE (HRESULT: 0x88980406)' What fixes or workarounds can I use to prevent my application from crashing. I have tried to listen to SystemEvents.DisplaySettingsChanging or WM_DISPLAYCHANGE and stop rendering for 5 seconds but it had no effect. So it seems that the problem is unrelated to my application and WPFDXInterop and is caused by the D3DImage Instead of using the D3D11Image, it uses the D3DImage directly. I could reproduce the same behaviour with the SharpDX Samples "WPFHost".
Sometimes when a Monitor is unplugged or when WIN+P is used to change the Projection options, my application crashes with UCEERR_RENDERTHREADFAILURE. My application renders its content with D3D11 and I present it with a D3D11Image from WPFDXInterop.
