Starting from Windows Vista and in Windows 7, when an application stops responding and detected by the OS, its window content will be blurred until is killed. I am not sure if it is called blurring, or fading, or something else. But how can I implement this effect in D3D11? Thanks.

Pretty easy with that Shader

float4 PixelShader(VertexOut input) : COLOR0
{
    float4 Color;
    Color =  tex2D(ColoredTextureSampler, input.textureCoordinates.xy);
    Color += tex2D(ColoredTextureSampler, input.textureCoordinates.xy + (0.01));
    Color += tex2D(ColoredTextureSampler, input.textureCoordinates.xy − (0.01));
    Color = Color / 3;
    return Color;
}

of course u can amplify it over time to achieve a "blurring out"

I tried your solution but unfortunately it is not effect I want. It is indeed like a low-pass image filter.
