[BUG] Freeze unavailable when opened

[ZaneH]

Summary

When I start the program with pkill -SIGUSR1 wayscriber or by manually starting it with wayscriber --active (after killing the daemon), I see "Freeze unavailable" for a few seconds until the message fades away.

Ctrl+Shift+F (the default freeze command) doesn't function it seems, I get a notification that it tried but motion is still visible on my desktop.

Steps to Reproduce

This issue happens immediately anytime I open the program.

Expected Result

For this warning not to show. I didn't see this behavior in older versions (unsure which version I started seeing this).

I would also expect that when freezing the screen, my desktop stays still, but it does not.

Configuration Details

1. wayscriber 0.9.10 -- it looks like 0.9.11 is available in nixpkgs-unstable, but for some reason my system isn't using that version. I'm trying to update it right now to see if that fixes it. edit: Having unrelated issues upgrading my system because of a new Python version. Hopefully 0.9.10 is fine...
2. daemon mode
3. Pretty certain I'm using the default config. Removing the config made no difference (made sure to restart the daemon)

Repro Frequency / Workarounds

Happens every time, I haven't found any workarounds. I tried a few environment variables with no luck (e.g. WAYLAND_DISPLAY)
