After upgrading to 4.11, the system tray stopped to show icons in 2 lines (the tray was rewritten with QML?). So, now the icons are very big, and small X ones even aren't correctly aligned which looks bad. Reproducible: Always
Created attachment 85353 [details] Bad system tray layout example (small Opera icon isn't aligned at all) Maybe you can add an option to display icons in 2 lines? It was also much more convenient because the tray didn't take so much space!
