Git commit ecf0cc36936f69830a07937b97807ec0ba4d3f41 by Marco Martin. Committed on 10/01/2022 at 09:22. Pushed by mart into branch 'master'. Don't crash when a screen gets disabled and enabled again when a screen gets disabled, the containment loses its view, and when gets enabled again, the process of the old orphaned containment getting a new view causes a plasma crash. It comes from the wallpaper, which indicates a hierarchy of C++ owned objects makes the internal one (wallpaper) to not reset correctly its window and have a stray pointer to it.
