Hi,
I'm try to render text on a ID3D11RenderTargetView/ID2D1RenderTarget
Text rendering works well
But when i set background to transparency this gone black

i allow Transparency on my mainwindows
device.ImmediateContext.ClearRenderTargetView(renderTargetView, backgroundBrush.Color);
d2dRenderTarget.BeginDraw();
d2dRenderTarget.Clear(backgroundBrush.Color);

backgroundBrush.Color => Color4(0,0,0,0)

Any ideas ?
Thanks
