Same problem here. (left) click on corner for resize gives orange square and right click menu. For me refocus almost never works to get rid of the issue and orange resize square stays fixed on all desktops (also when I move the LibreOffice window) untill I quit LibreOffice.
Some output when i start it from bash:
pc ~ $ libreoffice -writer
pc ~ $
(soffice:23991): Gdk-CRITICAL **: IA__gdk_window_get_events: assertion `GDK_IS_WINDOW (window)' failed
