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.

Git commit f88c6e3b23c2d060a7c773ed09506edf614fca1c by Nate Graham, on behalf of Niccolò Venerandi. Committed on 07/12/2023 at 00:27. Pushed by ngraham into branch 'master'. 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.
