OS error 4 from winit: "Interrupted system call"

Using latest master of iced. When I Ctrl-C in my application:

^Cthread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 4, kind: Interrupted, message: "Interrupted system call" }', /home/ploppz/.cargo/git/checkouts/winit-57d3141eaf559308/9c35895/src/platform_impl/linux/x11/mod.rs:360:54

This is my application https://github.com/Ploppz/bup/commit/62f344465837575620fbf5de92942b5663a51839

I have ctrlc handler, not sure if it matters:

    ctrlc::set_handler(move || {
        SHOULD_EXIT.store(true, std::sync::atomic::Ordering::Relaxed);
    })
