ebiten: calling Fill and Set, and resizing the window breaks the rendering

[hajimehoshi]

package main

import (
	"image/color"

	"github.com/hajimehoshi/ebiten/v2"
)

type Game struct{}

func (self *Game) Layout(w, h int) (int, int) { return w, h }
func (self *Game) Update() error              { return nil }
func (self *Game) Draw(screen *ebiten.Image) {
	screen.Fill(color.RGBA{255, 0, 0, 255})
	screen.Set(1, 1, color.Black)
}

func main() {
	ebiten.SetWindowResizable(true)
	ebiten.RunGame(&Game{})
}
