From my understanding with the help of AI it seems like the desktop app currently applies WDA_EXCLUDEFROMCAPTURE to its windows, which causes NVIDIA Shadowplay's Desktop Capture mode to shut itself off entirely whenever Proton Authenticator is open not just black out the window, but refuse to record at all.

This is mild infuriating if I wanna get a clip of something said in a discord with my homies or browsing the web and not being able to desktop capture on NVIDIA Broadcast.

A "Disable screen capture protection" toggle in Settings would let users opt out of this behaviour.

This would be useful for streamers and anyone who records their desktop regularly.
