Function send_cursor_frame 

pub(crate) fn send_cursor_frame(
    state: &AppState,
    output: &Output,
    time: impl Into<Duration>,
)

Answer the frame callbacks of a surface-backed cursor. Xwayland and libwayland-cursor clients wait for the cursor surface’s frame callback before attaching their next sprite, so a cursor surface that never gets one stops updating after its first sprite.
