It affects me too, but doesn't happen with all apps. Now I'm with firefox open and if I launch Chromium browser happens the same: it opens behind firefox but if I open libreoffice it opens properly. The behaviour with Clementine is like you comment and with others (not all) that you minimize to notification area too, for instance: Qbittorrent. Transmission behaviour is good and shows up at front when you open it from the notification area. (Sorry for my english)
