I'm also running it smoothly on Wayland+nvidia. Pacman install btw.
Most key bindings work ime. All commands I've tried in the past few days work fine too, though I've missed things especially for Python development. For Rust it is very much usable today I'd say.
I'm running it on Wayland + Nvidia (god help me) and it works great, no crashes whatsoever. No idea what's going on on your end.
I haven't tried using any custom keybindings or the command palette, so I'm not sure if those work.
Tried it today, didn't expect much, but I have to say I was pleasantly surprised at the speed and look and feel. I will give it a try for a while to see if I will switch from vscode permanently.
I'm surprised and disappointed they didn't mention Windows.
They publish macOS and now Linux releases. The issue tracker has many/multiple Windows tickets and a windows label. So it seems it's not published as a release yet, but potentially usable as self-compiled, with efforts to reach stability. I assume anyway. There's no obvious, clear indication or documentation that I can find (docs, readme tickets, project, milestone).
