FWIW, I would love this too. IMHO this should even be the default (but is obviously something for the https://phabricator.kde.org/tag/vdg/ to decide). Reasons: - The shadow not only adds a spatial dimension to the visuals, it also is important in separating the contents of cascaded windows. Currently, this second function is not achieved for the left and top borders. - It would be consistent with GNOME, Windows (all borders) and MacOS (all borders except the top). Patch LGTM. However, I noticed a small inconsistency (probably just food for thought and not something for this patch): Shadows of menus do not respect this, they are still offset. While that's the behaviour on Windows too, on MacOS menus have shadows on all three borders.
