Finally, explain the steps you took in plain English to reproduce the problem below.

First, create and run a Gio program. Using Go 1.13,

$ cd $(mktemp -d)
$ go mod init example.com
$ cat > crash.go
package main

import (
	"fmt"
	"log"

	"gioui.org/app"
	"gioui.org/io/system"
	"gioui.org/op"
)

func main() {
	go func() {
		w := app.NewWindow()
		if err := loop(w); err != nil {
			log.Fatal(err)
		}
	}()
	app.Main()
}

func loop(w *app.Window) error {
	first := true
	ops := new(op.Ops)
	for {
		e := <-w.Events()
		switch e := e.(type) {
		case system.DestroyEvent:
			return e.Err
		case system.FrameEvent:
			ops.Reset()
			e.Frame(ops)
			if first {
				w.Invalidate()
				fmt.Println("invalidated")
			}
		}
	}
}
$ go run .

Then, use shift-super-q to quit the Gio program.

You may have to do it several times to trigger the crash.

[emersion]

Moving to wlroots since the stack trace doesn't contain any sway symbol.
