Though I assume you’re a KDE user and thus waiting for Kalpa to become mature before a test ride.
That’s right!
Could you elaborate on what you didn’t like about Aurora and Bazzite;
Bazzite comes with Lutris and Steam preinstalled as native packages. I don’t use Lutris and want to use Steam as flatpak, so I decided to try Aurora.
For some reason it was surprisingly unstable. I’ve had various issues with KDE, DXVK and a few mainstream errors, that I had to either try to fix myself (like this one) or simply ignore (like this one). I’ve switched back to openSUSE and now I’m happier than ever about openQA existence.
