Have a look at this https://www.codeproject.com/Articles/20651/Capturing-Minimized-Window-A-Kid-s-Trick

you can capture the entire client area of a partially covered window, you can even capture the entire client area of a minimized window. Of course, it's C code but, it's fairly simple and it wouldn't take much to port it to FPC.

Enjoy!
