AppIndicator Icon Labels Absent After Return From Lock Screen in GNOME EXCEPT on Fedora

On Debian 12 / 13, Ubuntu 24.04 and openSUSE Tumbleweed under GNOME when the desktop resumes from a lock screen, any appindicator which has a label (in addition to the icon) only shows the icon. The label returns when the appindicator does its own refresh (open the appindicator Preferences and click OK).

This DOES NOT occur on Fedora 42 / 43.

I suspect that something changed within GNOME (so no longer does a refresh on return from screen lock) and that Fedora does kick off some sort of refresh (and the others do not).

Can anyone shed light on this suspicion please?

If there is some sort of refresh which Fedora calls I’m hopeful that maybe I can call that or perhaps use DBUS or some other mechanism to detect when screen lock is broken and then refresh the indicator myself (as I have written these indicators).

More details on the versions of distributions which I have tested can be found here.

Thanks,

Bernard.
