[🐛 Bug]: Headless Mode Results in White Screen in Selenium [C#]

[serizava01]

What happened?

I have encountered an issue while using Selenium with the headless argument. When running the browser in headless mode, the page renders as a blank (white) screen, even though the site works fine when running in non-headless mode. The page appears to load successfully (based on network logs and console messages), but no content is visible.

Steps to Reproduce:

Set up a Selenium WebDriver (Chrome) with the headless option enabled.
Navigate to a webpage that renders correctly in non-headless mode.
Observe that the content does not display, and the screen remains white in headless mode.
Expected Behavior: The page should render as it does in non-headless mode, displaying the full content.

Actual Behavior: The page appears as a blank white screen

Thank you!

How can we reproduce the issue?

ChromeOptions options = new ChromeOptions();
            if (!checkBox1.Checked)
            {
                options.AddArgument("--headless");  
                options.AddArgument("window-size=1920x1080");
               
               
            }
            ChromeDriver driver = new ChromeDriver(options);
            driver.Navigate().GoToUrl("https://www.google.com/");

change
options.AddArgument("--headless")
on
options.AddArgument("--headless=old")

Depending on the new headless mode, now you can use --headless=old, but Selenium should make it more compatible so that it detect when to use --headless or --headless=old. Because me myself I am not sure when to use these in a project I want to publish soon and it should be compatible.

I am confused of what versions of Selenium and Chrome the --headless or --headless=old should be used, also be sure that only the new headless mode will be used in upcoming updates of Chrome depending on that they say:

Did you fix it by using "--headless=old" instead? @serizava01
