Help Can I bypass a process using setWindowDisplayAffinity to hide from capture?

[eliakim63]

There's a certain process that's using setWindowDisplayAffinity to hide the whole screen from getting captured. I'm guessing it has a window that takes up the whole screen and is set to ignore clicks and is transparent so users can, but with setWindowDisplayAffinity set to WDA_MONITOR, any other processes attempting to capture the screen sees nothing but blackness.

Is there a way to bypass that?
One solution I could think of was either injecting a dll into that process and calling setWindowDisplayAffinity with WDA_NONE, and Idk if this is possible, but another way I thought of was hooking that setWindowDisplayAffinity and then doing nothing and returning successful result to caller.

I could test those and see for myself, but I wanted to know if there are other methods since I'm not sure if the process I'm targeting checks whether it's been tampered with or not.

Thanks

Try with _WinAPI_PrintWindow.  It seems to be working just fine with this affinity.

Try turning off (End Process) dwm.exe in task manager and see if that helps, SetWindowsDisplayAffinity only works if the desktop is composed with dwm..

That doesn't work, it closes and opens

I doubt that user will answer.
I'd say: don't use that "certain process".
