Here is a very helpful comment from Thomas Lübking from kde-bugs #341930:
KWin is not responsible for restarting applications.
This bug was *only* about not restoring window manager attributes (position,
virtual desktop, etc.) on session restorage.
There're fundamental bugs in Qt5 that prevent (both, correct and entire)
restoring of Qt5 applications, see
