Rod Version: v0.114.5

The code to demonstrate your question

1. Clone Rod to your local and cd to the repository:

   git clone https://github.com/go-rod/rod
   cd rod

2. Use your code to replace the content of function TestRod in file rod_test.go.

3. Test your code with: go test -run TestRod, make sure it fails as expected.

4. Replace ALL THE CONTENT under "The code to demonstrate your question" with your TestRod function, like below:

package main

import (
    "github.com/go-rod/rod"
    "github.com/go-rod/rod/lib/launcher"
    "github.com/go-rod/rod/lib/devices"
    "os"
    "log"
    "fmt"
    "time"
    "os/signal"
    "syscall"
)

var err error
func main() {
    l := launcher.New().
    Headless(false). 
    Devtools(false).
    Env(append(os.Environ(), "TZ=Asia/Tokyo")...).
    Leakless(true)
        
    url, err := l.Launch()
    if err != nil {
        fmt.Println("Error launching browser:", err)
        return
    }
    defer l.Cleanup()
        
    browser := rod.New().ControlURL(url).DefaultDevice(devices.LaptopWithHiDPIScreen)
    if err = browser.Connect(); err != nil {
        fmt.Println("Error connecting to browser:", err)
        return
    }
    defer browser.MustClose()
    page := browser.MustPage() 
    page.Navigate("https://browserleaks.com/javascript")

    ticker := time.NewTicker(30 * time.Second)
    quit := make(chan struct{})
    go func() {
        for {
            select {
            case <-ticker.C:
                log.Println("some code")
            case <-quit:
                ticker.Stop()
                return
            }
        }
    }()

    sigs := make(chan os.Signal, 1)
    signal.Notify(sigs, syscall.SIGINT, syscall.SIGTERM)

    <-sigs
    close(quit)
    fmt.Println("browser closed")
}

What have you tried to solve the question

Original device definition：

LaptopWithHiDPIScreen = Device{
		Title:          "Laptop with HiDPI screen",
		Capabilities:   []string{},
		UserAgent:      "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36",
		AcceptLanguage: "en",
		Screen: Screen{
			DevicePixelRatio: 2,
			Horizontal: ScreenSize{
				Width:  1440,
				Height: 900,
			},
			Vertical: ScreenSize{
				Width:  900,
				Height: 1440,
			},
		},
	}

Delete the Vertical part of the definition and it will display normally. The default display is to select Horizontal or vertical. Where to control it?

Change your code from:

browser := rod.New().ControlURL(url).DefaultDevice(devices.LaptopWithHiDPIScreen)

To:

browser := rod.New().ControlURL(url).DefaultDevice(devices.LaptopWithHiDPIScreen.Landscape())
