Hey, folks. Just a heads up: today's Rawhide has a new Qt which seems to make SDDM crash on startup, so the system boots to a black screen and you can't log in. So, updating may not be a great idea!
I've filed this as https://bugzilla.redhat.com/show_bug.cgi?id=2139465 and https://github.com/sddm/sddm/issues/1608 . Unfortunately haven't been able to get a usable backtrace yet.
Thanks to Aleix Pol, we figured this was due to a missing rebuild of layer-shell-qt , which uses private Qt symbols and so needs rebuilding for each new Qt version. I did that rebuild and KDE's fine again in today's Rawhide, so resume updating. :D
