Oh, actually I think this was a side effect of a different problem: I had a USB ethernet dongle attached which, for some reason, was connecting and disconnecting rapidly. So probably the applet tried to refresh every time this happened. I guess ideally it would still be usable even in this situation, but probably this is not really an issue. I'll investigate the ethernet dongle issue separately.

Since upgrading to 23.10, when you open the applet's menu and hover over a submenu such as "Available networks" or "VPN Connections", the submenu appears and disappears rapidly (about twice per second), and if you try to mouse over the submenu it disappears completely. This makes it impossible to select an available network, etc. It worked fine under 23.04.
