Clear doesn't work on KDE X11

[Exidex]

When developing Gauntlet I faced problem with clear() not working on KDE X11, same code works on Gnome X11 and on KDE Wayland

fn main() {
    let mut clipboard = arboard::Clipboard::new().unwrap();

    clipboard.clear().unwrap();
    clipboard.set_text("").unwrap();

    std::thread::sleep(std::time::Duration::from_millis(1000))
}
