+    [kcmkwin/compositing] Do not write GLPlatformInterface config
+
+    Summary:
+    The gui element to select the platform interface is dropped. Thus we
+    should not store the config for it. This is rather important as changing
+    compositor settings on Wayland would result in egl being written into the
+    config which potentially breaks an X11 session.
