[bug] SIGSEGV: Segment Violation with Progress Bar

What happend?

This code worked in v0.7. Updating to v0.8.1 causes a segment violation at runtime.

Code example

main.go

//go:embed assets/*
var assets embed.FS
var (
	logo *image.RGBA
	window *giu.MasterWindow
)

func main(){
	window = giu.NewMasterWindow(
		"Updater",
		377, 144,
		giu.MasterWindowFlagsFrameless|giu.MasterWindowFlagsNotResizable|giu.MasterWindowFlagsTransparent,
	)
        logo, _ = loadImage(assets, "assets/logo.png")
	window.Run(defaultUI)
}

func defaultUI() {
	giu.SingleWindow().Layout(
		giu.Align(giu.AlignCenter).To(
			giu.Dummy(0, scaleDivider(6)),
			giu.ImageWithRgba(logo).Size(80, 80),
			giu.Dummy(0, scaleDivider(6)),
			giu.ProgressBar(ReadProgress()).Size(scaleValueX(377)*0.75, scaleValueY(5)),
		),
	)
}

func scaleDivider(value float32) float32 {
	_, yScale := giu.Context.Backend().ContentScale()
	if yScale > 1.0 {
		value *= 2
	}
	return value * yScale
}

func scaleValueY(value int) float32 {
	_, yScale := giu.Context.Backend().ContentScale()
	return float32(value) * yScale
}

func scaleValueX(value int) float32 {
	xScale, _ := giu.Context.Backend().ContentScale()
	return float32(value) * xScale
}

func loadImage(assets embed.FS, path string) (*image.RGBA, error) {
	data, err := assets.ReadFile(path)
	if err != nil {
		return nil, err
	}

	img, err := png.Decode(bytes.NewReader(data))
	if err != nil {
		return nil, err
	}

	return giu.ImageToRgba(img), nil
}
