[Bug]: Blank screens visible on headless mode.

[Kedar-Ghadge]

Version

1.44.0

Steps to reproduce

Example steps (replace with your own):

1. Clone my repo at https://github.com/Kedar-Ghadge/PlaywrightWithNunitCSharp.git
2. Make changes in runsettings file, change headless mode to true.
3. execute command dotnet test from the project's folder path
4. You should see blank screens come up without any taskbar icon for same.

Expected behavior

No blank screens should occur.

Actual behavior

Blank screens are occurring on test execution.

Additional context

• If I put wrong spelling for true like instead of 'true' if I put 'ture' then no blank screen is occurring.

Environment

• Operating System: [Windows 11]
• CPU: [x64]
• Browser: [Chromium]
• .NET Version (TFM): [net8.0]
• Other info:

Looks similar to these issues:

• Chrome 129 headless Error hardkoded/puppeteer-sharp#2782
• [Bug]: white square when you activate "headless" in the new version of chrome. puppeteer/puppeteer#13121
• [Bug]: Window appears after launch() puppeteer/puppeteer#13012
• https://stackoverflow.com/questions/78996364/chrome-129-headless-shows-blank-window

For me it looks like the issue is no longer present with chrome/edge 130.
I am supprised that I coulnd't find a playwright issue for it.

If I put wrong spelling for true like instead of 'true' if I put 'ture' then no blank screen is occurring.

For me the test fail immediatly when using incorrect spelling.

@Kedar-Ghadge have you tried a more recent Playwright version? e.g. 1.47?

[Kedar-Ghadge]

Let me try with lastest Playwright version and let me check with my browser version as well. One more observation I have. If I remove channel from runsettings file then also I am not getting any blank screen

This means that updating won't help - since msedge still uses your system Microsoft Edge which you have installed.

You can try Microsoft Edge Beta / Dev if you need to use Edge and can't use Playwright's Chromium.

[mxschmitt]

I see that you don't use the latest Playwright version. The other folks in the issue suggest that updating the Playwright version should make it work with recent Microsoft Edge.

@mxschmitt, it worked after upgrading playwright to 1.47.0 latest version. Thanks.
