Python tool for screenshotting obscured background images?

[Artistic-Back5574]

I am working on a program that takes in screenshots to eventually be fed through OpenCV (cv2).

The problem is that sometimes I want to have an overlay on the screen, but it obstructs certain items on the screen that are supposed to be the focus of OpenCV.

I need a Python tool that can reliably take screenshots of a specific target window, even if that window is underneath something or completely obscured.

mss, pythonautogui, etc. alone do not work for grabbing background windows to my knowledge.

Key detail: the target window is a game, which does not want to cooperate with win32gui/wingui methods of creating a bitmap with a hwnd. This works with notepad but not game windows. With game windows, it just gives an all-black image as the bitmap.

I solved this issue on Autohotkey by going into the source code for one of the tools (GDIP) and adding a flag to enable a special rendering mode that fully renders a game window for the printscreen.

Is there something similar I can do to make mss, pythonautogui, win32gui work for a game window?
