Screenshot using SharpDX and EasyHook transparent - screenshot

Question

I have been struggling in taking screenshots with DirectX, the problem is, it's working but seems to be missing some colors (black outline is missing for example), and some stuff that is also rendered by DX doesn't show.
I have uploaded the images (how the image should render and the rendered one) and also the code, what might be the issue?
Correct Image
Rendered Image
Greetings
