Set --hide-crash-restore-bubble by default to prevent Chromium window from opening after unsuccessful shutdown.

[razor999920]

Is there an existing issue for this?

• I have searched both open/closed issues, no issue already exists.

CefSharp Version

126.2.70

Operating System

Windows 11

Architecture

x86

.Net Version

8

Implementation

WPF

Reproduction Steps

I have no been able to pin point the cause for this issue. It happens every 2/3 times of me opening my applicatio.

Expected behavior

There should be no chromium browser tab or any other window opening besides the application.

Actual behavior

When I open my WPF application, it opens a chromium browser tab

Regression?

When I downgrade the version the problem goes away but this happens when I upgrade to 126.7.2 or new versions.

Known Workarounds

Downgrading the version resolves the issue for now.

Does this problem also occur in the CEF Sample Application

Yes using WPF/OffScreen command line args

Other information

After going through all the issues, it seems only I have having this problem and I'm assuming I'm missing something during my CefSetting initialization.

Following is my code:
App Startup:
`
private void Application_Startup(object sender, StartupEventArgs e)
{
var settings = new CefSettings()
{
ChromeRuntime = true,
LogFile = "Debug.log",
LogSeverity = LogSeverity.Verbose,
CachePath = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "CefSharp\Cache"),
};

    // //Perform dependency check to make sure all relevant resources are in our output directory.
    // settings.CefCommandLineArgs.Add("disable-gpu", "1");
    // settings.CefCommandLineArgs.Add("disable-gpu-compositing", "1");
    // settings.CefCommandLineArgs.Add("disable-extensions", "1");
    // Cef.Initialize(settings, performDependencyCheck: true, browserProcessHandler: null);

    Cef.Initialize(settings);

    // Open Window
    MainWindow mainWindow = new MainWindow();
    mainWindow.Show();
}

`

MainWindow.xaml
`

<Border>
    <cefSharpWpf:ChromiumWebBrowser Name="Browser" />
</Border>

`

MainWindow.xaml.cs
`
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();

    Browser.LoadUrl("www.google.com");

}
}
`

Thank you @amaitland the issue seems to be with the runtime. When i switched back to alloy the issue seem to be resolved.
I have also filed this issue in the CEF repo and following is the link: chromiumembedded/cef#3767

@razor999920 Thanks 👍

Based on comment chromiumembedded/cef#3767 (comment)

I think it might be worth setting --hide-crash-restore-bubble by default.

Renaming and reopening this issue.
