So this is an interesting issue that has just started with Window 10 64bit update 20H2, and Radeon driver update 20.12.1. While in game and streaming, everything is just fine for a bit, but then at random it just goes to a black screen on twitch (the stream). I try to open the in game Radeon UI, and after 2 or 3 failed attempts, it'll open outside that game while at the same time, collapse the game to the task bar.
If I stop the stream from there and close out the UI, and maximize the game again, and do the hotkey combo to start streaming again It'll function like normal (sometimes, other times I need to quit out of the game completely.)
Now everything was fine yesterday (before the Windows 10 20H2 update) could stream for up to 2 hours, but now I can't stream stably between 10 to 30 minutes before this issue happens again.
I've tried changing power saving modes to high performance to stop anything from going to sleep. Made sure my twitch stream bitrate is 6000 or less (Twitch requirements). I'm running out of ideas to try.
