x11 running two window creation/deletion panics

[gui1117]

extern crate winit;

fn main() {
    for _ in 0..2 {
        let mut events_loop = winit::EventsLoop::new();

        let _window = winit::WindowBuilder::new()
            .with_title("A fantastic window!")
            .build(&events_loop)
            .unwrap();

        events_loop.poll_events(|event| {
        });
    }
}

it panics on unwrap None at https://github.com/tomaka/winit/blob/master/src/platform/linux/x11/mod.rs#L360
and then if I fix that it panics on https://github.com/tomaka/winit/blob/master/src/platform/linux/x11/mod.rs#L719

It seems that FocusOut and ConfigureNotify events are sent after window deletion.
A solution would be to return when windows.get_mut(..) returns None on those events. Or maybe on all events.

This appears to be a duplicate of #414, which means this should be resolved by #416.

(Also, this isn't related to your issue, but as general usage advice, my understanding is that you should only create one EventsLoop and use it for all windows.)

#416 doesn't solve the issue panic happens at https://github.com/francesca64/winit/blob/x11-drop-window/src/platform/linux/x11/mod.rs#L375

(i agree for one eventsloop)

I've updated the code such that all cases should be covered now. Does everything work fine now?

[gui1117]

yes thanks !

Fixed via #416
