The Flatpak on GNOME has no X11 (fallback-x11 on a Wayland session) and GNOME offers
no data-control protocol, so arboard::Clipboard::new() failed every time. The handle
was kept only on success, so the background Paste check reconnected to the compositor
and logged a warning every 250 ms: 267k warnings in 18 h, the 16 MB log full in 3 h.
- A clipboard that can't be opened is tried again after 1 s, doubling to a minute.
A Copy or Paste of the user's retries at most once a second.
- The outage is logged once (WARN) and its end once (INFO), across the UI's and the
background check's handles.
