I’ve had some VERY similar issues with SDDM ever since I switched to Fedora 40 Sway. Only my issue is with Qtgraphicaleffects, while quickcontrols seems to load properly. I have the following package: qt5-qtquickcontrols2
installed with dnf and it works. Hope it works for you too. But for me, I’m still having Qtgraphicaleffects issues, to the point I ended up rewriting my sddm theme without Qtgraphicaleffects. It’s crazy, I know, but it’s hard enough to find a decent theme without KDE dependencies as it is (I’m not using KDE Plasma). Finding one without qtgraphicaleffects as well would be even harder.
