Remote play is already semi-broken on stable. In the sense that the video renders super dark unless you disable hardware decoding.

The beta and preview channels are even worse. The remote play session will just never load at all.

It seems like this is slipping through the cracks. I’m making this post to raise some awareness on the issue. Not sure what we can really do though.
Edit: God damn it valve.
Your fears were right, looks like this just got pushed to stable unfortunately.
Edit: They’ve pushed an update to fix this
Nice! Anyone confirmed that this works?
I was able to start a stream session and it did come up, although it kept reporting connectivity quality issues and it seemed like it was streaming at really low-bandwidth.
However, I normally stream via Sunshine/Moonlight and haven’t tried the native Steam version in a while since it normally doesn’t work well for me, so I think that’s something on my end rather than it being a bug (and the fact that it displayed the game to me indicates its no longer this bug, since it initialized and was at regular brightness).
