Issue report by another community member (see ):
Under GNOME, the quick starter icon doesn't appear to have a transparent background. An easy way to reproduce this behaviour is to set your GTK theme to New Wave and enable the LibreOffice Quickstarter in Tools > Options > Memory > Enable systray quickstarter. It would look a lot better if we removed the opaque background beneath the icon.
Reason why this happens
IIRC if a program uses EggTrayIcon or X11TrayIcon (or similar) instead of Gtk.StatusIcon, the icon does not contain a transparent background. All we need to do is change the code to use Gtk.StatusIcon (should be relatively simple).
 Original mail and screenshot:
Strange that the screenshot shows the OOo quickstarter icon...

The icon has been replaced by The Document Foundation symbol, the sheet of paper. It is transparent and looks fine in my gray GNOME theme. I am not sure who fixed this but it works now :-)
