Hello,
I can reproduce the problem as well.
My plasma/breeze window decorations are gone. Yesterday the following
packages were upgraded to 4:5.19.5-3:
libkdecorations2private7
libkdecorations2-5v5
libkf5screen-bin
libkf5screen7
If I try to open the window decoration settings dialog, the whole system
settings window crashes reproducable.
Application: systemsettings5 (5.17.5)
Qt Version: 5.15.1
Frameworks Version: 5.74.0
Operating System: Linux 5.9.0-1-amd64 x86_64
Distribution: Debian GNU/Linux bullseye/sid
The crash can be reproduced every time.
-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Segmentation
