Nvenc not suitable for streaming? (Green screen)

Hi, so I’m using Nvenc + Live555 for streaming some OpenGL rendering. I’ve found that, in certain ocassions, the stream produced is a completely green screen. Trying to find out the reason, I found this topic on the OBS forum : https://obsproject.com/forum/threads/nvenc-twitch-green-screen.14691/

Is Nvenc not good for streaming? Has anybody else found green screens?
