[SDK BUG] Transparence Issue on DX11!

[ZaweSec]

Hi, im using the directx 11 sample of visual studio and ported it to the gamebar, i have AllowForegroundTransparency to true and the alpha mode to DXGI_ALPHA_MODE_PREMULTIPLIED;

this is the render:

bool App1Main::Render() 
{
    // Don't try to render anything before the first Update.
    if (m_timer.GetFrameCount() == 0)
    {
        return false;
    }

    auto context = m_deviceResources->GetD3DDeviceContext();
    DXGI_SWAP_CHAIN_DESC1 desctest;
    m_deviceResources->GetSwapChain()->GetDesc1(&desctest);

    // Reset the viewport to target the whole screen.
    auto viewport = m_deviceResources->GetScreenViewport();
    context->RSSetViewports(1, &viewport);

    // Reset render targets to the screen.
    ID3D11RenderTargetView *const targets[1] = { m_deviceResources->GetBackBufferRenderTargetView() };
    context->OMSetRenderTargets(1, targets, m_deviceResources->GetDepthStencilView());

    // Clear the back buffer and depth stencil view.    
    DirectX::XMVECTORF32 ClearColor = { { { 0, 0.0f, 0.0f, 0.f } } };

    context->ClearRenderTargetView(m_deviceResources->GetBackBufferRenderTargetView(), ClearColor);

    return true;
}
