Description Jin Liu 2023-12-02 02:28:35 UTC

STEPS TO REPRODUCE
1. Set a panel as "floating".
2. Maximize a window, so the panel de-floats.
3. `systemctl restart --user plasma-plasmashell.service`
4. Panel shadow will disappear.
5. Restore the window, so the panel floats.
6. Now the shadow will re-appear.

Update panel shadows after change in QML values

During startup, QML values might be initially incorrect; when they
change, the shadow isn't updated accordingly. This fixes the issue.
