Description

Add Option to Disable “Sharing Tab to [site]” Banner in Tab Sharing

Who's implementing?

I'm willing to implement this feature myself

The problem

When using getDisplayMedia or tabCapture APIs to capture a specific browser tab for advanced applications (e.g. transcription services), a persistent banner appears at the top of the shared tab that reads:

“Sharing this tab to [destination domain]”

This UI element is unremovable, overlayed, and disruptive to the user experience

Possible solutions

Introduce a permission or flag (either via API or command line) to:

Disable the banner via dev tools or manifest permission

Suppress the banner for trusted domains or localhost (dev environments)

Allow capture sessions with a banner: false flag (similar to how camera/mic UI is sometimes hidden in fullscreen apps with explicit user permission)

前提条件: Chromium codebase navigationC++ programmingChromium build systemungoogled chromium patching process
初心者向け度: 15
調査方針: Start by searching for the banner text (e.g., 'Sharing this tab to') in the Chromium source code, likely in chrome/browser/media/webrtc/ or similar. Identify where the UI component is rendered and how it can be conditionally hidden. Look at existing ungoogled chromium patches that modify UI behavior for examples. Consider adding a command line switch or a new entry in chrome://flags. The issue number is 3374; review any comments or linked PRs for additional context.
