redraw the data several times in the console

[pheninux]

hello,

I have question, why when I change the size of my console does it redraw the data several times in the console?

see screenshot

this is my code :

package main

import (
"fmt"
tea "github.com/charmbracelet/bubbletea"
"github.com/charmbracelet/lipgloss"
"strings"
)

var (
with = 200
// Dialog.
BoxStyle = lipgloss.NewStyle().
Border(lipgloss.RoundedBorder()).
BorderForeground(lipgloss.Color("80")).
Padding(0, 0).
BorderTop(true).
BorderLeft(true).
BorderRight(true).
BorderBottom(true)

forcolor1 = lipgloss.NewStyle().Foreground(lipgloss.Color("98"))
forcolor2  = lipgloss.NewStyle().Foreground(lipgloss.Color("30"))
separator = lipgloss.NewStyle().SetString("❣").Foreground(lipgloss.Color("40")).Padding(0,1,0,1).String()
)

type model struct {
out string
}

func (m *model) Init() tea.Cmd {
return nil
}

func (m *model) Update(msg tea.Msg) (tea.Model, tea.Cmd) {
switch message := msg.(type) {
case tea.KeyMsg:
switch message.String() {
case "q":
return m, tea.Quit
}

case tea.WindowSizeMsg:
	with = message.Width
	return m, nil
}
return m, nil
}

func (m *model) View() string {

sb := strings.Builder{}
sb.WriteString(lipgloss.JoinHorizontal(lipgloss.Center, forcolor1.SetString("Hello").String()+separator+forcolor2.SetString("World").String()))
m.out = lipgloss.Place(with, 0, lipgloss.Center, lipgloss.Top, sb.String(), lipgloss.WithWhitespaceChars(""))

return BoxStyle.Width(with - 2).Render(m.out)
}

func main() {

m := model{}

if err := tea.NewProgram(&m).Start(); err != nil {
	fmt.Println(err)
}
}
