I already have a small Python-based server/client that displays an overlay and another overlay that is triggered under certain triggers, yet the moment the program switches the overlay on it takes focus away, worse, grabs keyboard and mouse focus. What I need is a clean way to keep custom graphic elements—mainly semi-transparent PNG images plus a few lines of text—visible above any fullscreen window on Windows while leaving all input and focus with the underlying application. I am happy to stay in Python if the goal can be reached with the right combination of Win32, DirectX, or Vulkan hooks, but I’m open to C, C++, C#, or any language that clearly demonstrates stability and very low latency. The finished code should render at least 60 FPS, support per-pixel alpha, and cope with DirectX 9/11/12 as well as OpenGL titles without stuttering or flicker. Deliverables • Source code and a minimal compiled example that draws a test image and a sample text string over a fullscreen game or video player without stealing focus. • Clear build/run instructions and any third-party libraries referenced. • A short note on how to extend the draw routine so I can swap in my own images and text strings from the existing Python server. Acceptance criteria The overlay must stay visible in true fullscreen, alt-tab correctly, and allow continuous keyboard and mouse use in the underlying program without a focus change or noticeable frame-rate drop. I can provide all current python code for the server and client programs along with current overlay png files. if you need a run down on how the app works, please reach out
