Did this ever get sorted? I'm having the exact same problem!
I just don't understand. OBS running at 64GB??
Actually, yeah.I found that when I was running my Logitech webcam at full resolution, the memory leak would just slowly start ticking. But when I put it down 1 or 2 resolution levels it stopped happening. I'm still not sure why in the world that would be causing it, but it definitely was the culprit.
Sorry for not reporting in sooner, been a crazy month!k
