**I digged out the source:**

applying

```auto
-- priority: -1
event.listen {
  name = 'hooks:renderTopWidgets',
  run = function(e)
    if not editor.getUiOption("darkMode") then
      editor.setUiOption("darkMode", true)
    end
  end
}

```

and `Client: Wipe` + `Reindex` will cause this problem.

while replaced by

```auto
-- priority: -1
event.listen {
  name = "hooks:renderTopWidgets",
  run = function(e)
    if not clientStore.get("darkMode") then
      clientStore.set("darkMode", true)
      editor.reloadUI()
    end
  end
}

```

there’ll be no problem then.

**Seemingly unrelated huh?.. but it just happened…**

the whole story origins from that I don’t what [the flash caused by editor.reloadUI()…](https://community.silverbullet.md/t/permanent-dark-mode/370/9) then I came up with the `editor.setUiOption("darkMode", true)`, then here comes the problem…
