Hi,

When i use Windows capture to capture a Microsoft PowerPoint or a video call on Facebook, it shows only a blank screen. It does not show either the powerpoint nor the chrome page that has the Facebook messenger call.

If i try to open facebook video call as a Browsersource instead of windows caption source, it preview a page that asking me to login to facebook. But i can’t login because it is only a preview

I am using OBS 19.0.3 and windows 10

Kindly help

Excellent tip! Thanks. For the lessons to my students so far I have not been able to record Powerpoint presentations containing videos or clips with OBS, which appeared with a black or white box. I took off hardware acceleration in Crome and managed to record presentations with videos.
