I use libvirt to manage my virtual machines. By default it uses port 5900 to display VM's graphics [1]. Sometimes I start vino-server only after starting some VMs. Then obviously vino-server fails to bind to port 5900. Because of that I have used dconf-editor to set

/desktop/gnome/remote-access/alternative-port 8900
/desktop/gnome/remote-access/use-alternative-port true

Now vino-server correctly binds to port 8900. However, here's the quirk:

1. If I start vino-server prior to any VM, everything works. I can connect using VNC viewer (to port 8900). Even when I start some VM afterwards (and it binds port 5900), I can still connect to vino-server.
2. If I start some VM first (which binds port 5900) and vino-server second (which binds port 8900), I can't connect to the vino-server. It is completely stuck and it is not possible to connect to it. There is something very fishy.

This issue is very inconvenient, because I often encounter this use case:
start vino-server -> start VM -> connect to vino-server (OK) -> work, work, work -> vino-server crashes -> vino-server is automatically restarted -> I can no longer connect to vino-server
