Question / Help Black screen & preview when trying to record/stream

[Henjer]

When trying to record or stream Runescape my preview, stream and recording output all show a black screen. Audio does get picked up just fine. I am talking about the Runescape NXT client. I have tried using a window capture and game capture as source, but none of them work. Screen capture does work, but id rather not have people see the rest of my desktop and stuff :p

Maybe worth mentioning, i have tried running OBS Studio as Administrator, and i have also tried using OBS Classic instead, but neither works :(
