Matrix, and there’s a P2P one that just went around called PeerSuite? Both are far from perfect, but at least aren’t yucky corpo platforms. Sorry to come across so harsh in the initial comment, the tone in my head was light hearted I promise lol. More of a “I’m happy to help figure out an alternative communication stream in order to make me a useful tester.” Might be worth making your game a Mastodon account to direct people to from the Steam page? Could be a good spot to encourage people to learn about the fediverse and provide a channel for updates and a message system for testers? Idk. Discord is somewhat unique still in the type of organizational tools it provides, hence the love-hate relationship I have with it lol
I use Sunshine/Moonlight, OBS, Discord screen share, all on Wayland and an AMD GPU. No issues, both on my old Arch install and now NixOS. Every now and then there’s some issues in the actual updates that get pushed to these things, but those aren’t usually specific to my system. For example just recently an update was pushed to the loopback module OBS uses for virtual camera, but the OBS update that utilized it hadn’t been pushed yet, so I got a crash.
