SDL3 -Fenster kann D3D11 Swapchain nicht angezeigt werden ⇐ C++

[Anonymous]

Ich habe meine eigene Game Engine mit SDL3 und DX11 geschrieben. Ich konnte das HWND erhalten und auf swapchaNDesc.outputWindow einstellen und die Farbe auf Pink einstellen:

Aber das Fenster ist schwarz, obwohl es rosa sein soll? https://github.com/adoseofcodeyt/doctrinasdk
