GTK+ broke their systray icons (perhaps only in non-composited environments; I'm not entirely sure). As far as I know, version 3.24 is affected. This bug was introduced in https://gitlab.gnome.org/GNOME/gtk/commit/01d1bc3c75fd0eff5665f5b9c690c5e1e6c65f13. Links to a couple of upstream bugs (and patches): https://github.com/awesomeWM/awesome/issues/1720 (Ignore the people talking about Qt for this; Qt also broke their icons ages ago) https://github.com/awesomeWM/awesome/issues/2449 (This talks about GTK 3.24 being affected) https://github.com/i3/i3/issues/3335 https://github.com/TomaszGasior/gtk3-mushrooms/issues/12 https://gitlab.gnome.org/GNOME/gtk/issues/1280 https://gitlab.gnome.org/GNOME/gtk/merge_requests/391/diffs (Sadly this merge request is inactive for about a month now...) > I have attached a screenshot with systray icons from nm-applet, nm-applet is definitely GTK+. > variety, I do not know this, but it depends on gir1.2-gtk-3.0, so likely also GTK+. > pasystray, Also do not know, but depends on libgtk-3-0. > hexchat, Uhm... definitely GTK+, but it depends on libgtk2.0-0, so this should not be affected by the breakage in GTK+3...? > and xfce4-power-manager.

In X11, a background of "ParentRelative" means that the window inherits the background of its parent window. So, systray implementations can set a background on the systray window and the individual systray icons then inherit this background. GTK+ switched all its windows to a background of "None". This means that no background at all is drawn and whatever was visible here before stays visible when a background should be drawn. This is the behaviour that GTK+ is getting. (Qt has (had?) a different problem; they simply grabbed a screenshot and used that as the background. So, if e.g. the screensaver was active at the time the systray icon became visible... well, you now get your screensaver as background. Sometimes it would also screenshot old systray icons etc.) Cheers, Uli -- Sent from my Game Boy.
