Capture Dotnet / Classic WPF windows

[Mitra-M]

Hello
Sorry, this may not be a good place to ask this question, but I think you are the only one who can help me.

I used to use BiBlt to capture off-screen WPF windows, but it is not working on windows1809 and later. (many people have this problem)

I saw new Microsoft capture methods, but unfortunately none of them can capture Dotnet/Classic WPF windows that whole or part of them are off-screen.
I would appreciate it if you could please give guidance on how I could do this?

In advance, thank you for the information.
Regards,
Mitra

@Symbai, Thanks for your reply , my problem is a little different than #2294, I have two simple (non-gaming) monitors let say M1 and M2, if I set the M1 to 50 Hz, my app locks at 50, which is not bad for me, but if I set the M2 to 75 Hz and run the program on the M2, the app will lock at 50 again while it is expected to lock on 75 Hz.
