lxqt/Lubuntu: Riseup-vpn icon doesn't show right on lxqt-panel system tray

Instead of the riseup-vpn icon, a generic cogwheel icon is shown on the systray of lxqt-panel. Lubuntu 19.04

changed milestone to %RiseupVPN 0.19.7

Can reproduce. It seems libappindicator might not work for LxQt, need to investigate a workaround.

mentioned in issue #156 (closed)

I'm not sure this is a clue or not but the correct icon does appear if the application is run as root. Perhaps this is some sort of permissions issue?

I also note there's a fairly recent commit to lxqt-panel regarding icons. It sounds a little different but it might be just the thing. If anyone else wants to give this a go, there is a Lubuntu CI PPA built from git master.

Sadly that last one is a no-go.

With #161 (closed) being closed, I thought maybe a similar fix might exist for this. I tried creating /var/lib/snapd/desktop/icons to begin to no avail. It looks like there's been issues with libappindicator mentioned upstream FWIW.
