Thanks for the report! Pretty sure I checked that it worked (but using LINE client, on GNOME), so maybe something specific to the Desktop Environment?
I am using XFCE in X11. For me the apps that work are iGetter download manager, SimHub, TrackIR 5, etc. Only Steam is still affected.
I noticed other side effects as well. If you launch three apps with systray icons (Steam + 2 others), the systray icons become responsive until one of the apps is closed. Then the Steam systray + the other one become both unresponsive, etc.
