+Subject: [PATCH] Add platform detection and adjustment to kded
+
+Summary:
+Current Plasma/master branch does no longer set the QT_QPA_PLATFORM env
+variable on Wayland. As kded is a process tightly connected to the
+workspace it also needs to pick wayland QPA in a Wayland session. This
+change brings in the adjustment from plasma-workspace and ensures that
+kded works correctly on any Wayland desktop environment, being it
+Plasma, GNOME or Weston.
+
+Test Plan: Restarted session, kscreen got layout correctly
