reopen 794573 thanks I'm reopening this as it is now broken in testing. This combination:
ii kwin-x11 4:5.3.2-3 ii kwin-style-breeze 4:5.3.2-2 Doesn't work and the user cannot login to a KDE5 session. The only workaround is to move kwin-style-breeze's /usr/lib/x86_64-linux-gnu/qt5/plugins/org.kde.kdecoration2/breezedecoration.so out of the way and then go to system settings and change the style to plastik. FWIW, I see the exact same issue with kwin-decoration-oxygen, leaving plastik as the only decoration that works.
