Describe the bug

When I compile the code below using fyne build --tags mobile it complains about window.ShowAndRun() not being called with a fyne.Do(..) wrapper, even though it's being called from the main thread.

How to reproduce

1. Compile the code below using fyne.io/fyne/[email protected] and the --tags mobile flag
2. run the resulting binary
3. Note complaints...

type MyWidget struct {
	widget.BaseWidget

	label *canvas.Text
}

func NewWidget(text string) *MyWidget {
	w := &MyWidget{}

	w.label = canvas.NewText(text, theme.TextColor())
	w.label.TextSize = 20.0

	w.ExtendBaseWidget(w)
	return w
}

func (w *MyWidget) CreateRenderer() fyne.WidgetRenderer {
	return widget.NewSimpleRenderer(w.label)
}

func (w *MyWidget) Dragged(e *fyne.DragEvent) {
	fmt.Println("DragEvent ", e)
	curPos := w.Position()
	dx, dy := e.Dragged.Components()
	w.Move(fyne.NewPos(curPos.X + dx, curPos.Y + dy))
}

func (w *MyWidget) DragEnd() {
	fmt.Println("DragEnd")
}

func (w *MyWidget) Tapped(e *fyne.PointEvent) {
	w.label.TextStyle.Bold = !w.label.TextStyle.Bold
	fmt.Println("Tap")
}

func main() {
	a := app.New()
	w := a.NewWindow("Drag Test")

	myWidget := NewWidget("Foo")

	cont := container.NewCenter(myWidget)

	w.SetContent(cont)
	w.Resize(fyne.NewSize(800,600))

[andydotxyz]

I cannot replicate here on macOS Sonoma.

Was this an M1/2/3 computer or Intel?

[pneumaticdeath]

This is on a M2 macbook air. I don't know what else might be different.
