Tried KDE Nobara after OpenSUSE and oh boy...
First Dolphin just crashed, always. Trying to report this caused even the crash handler to crash. Apparently there's a bug with encrypted setups and you have to manually create the thumbnail folder to fix this. No idea why this is not patched yet. Or maybe it is, but I can't further update the system anymore because of all packages throwing GPG errors now. This is all cursed to hell.
