I think it might be more of a Discord problem. I've experienced "a few weird crashes" on Windows, Mac, and Wayland GNOME. Windows being the most problematic in general.
idk how we can blame some JavaScript and html inside Firefox causing a Wayland crash as Discord’s fault. They’re like 9000 layers of abstraction away from whatever SIGSEGV caused the crash
Is this specifically to do with screen sharing or streaming? I use it purely as a chat client under Wayland and it has generally worked fine.
(Now that I think of it, I've had a few weird crashes, but nothing which made it unusable)
