Original GitHub issue: https://github.com/rivo/tview/issues/270

To match the background color with the terminal system background color, must set the SetBackgroundColor value to -1(tcell.ColorDefault).

Setting the BackgroundColor to -1 is works fine for most components, but for the List component produces unexpected results like below...

When the list is updated, the updated list and the previous list are overlapped.
When move the cursor down, the previous item remains in the selected background color.

Try

	app := tview.NewApplication()
	defer app.Stop()

	app.SetBeforeDrawFunc(func(s tcell.Screen) bool {
		s.Clear()
		return false
	})
