I’ve been using Fedora KDE on my own PC for a few years, but I’ve had some pretty severe breakages when updating. Though I suppose most of them happened because I had Cuda SDK installed, or monitor ICC profiles, but early on I also had Plasma crash on login while testing different themes. I’ll look more into Bazzite though!
Do you know how mature it is as a desktop OS? I saw the official FAQ does recommend against using it as such. I tried it on a HTPC a few years ago but at that point it didn’t seem very usable outside of Steam’s full screen UI.
