Google Chrome Tests Auto Picture-in-Picture for Covered Tabs

Google Chrome is testing a feature that automatically activates Picture-in-Picture (PiP) mode — a floating, resizable video window — when another application covers the browser tab playing a video.

The feature surfaced in Chrome Canary, the browser’s experimental pre-release build, and was demonstrated publicly in a YouTube video by the channel BrenTech.

How It Works

When a user plays a video in Chrome and then maximizes a separate application over the browser window, Chrome detects that its window is obscured and pops the video out automatically into a small floating player.

That player defaults to the bottom-right corner of the screen and is resizable.

Google controls the behavior through experimental settings called flags, located inside the browser’s `chrome://flags` menu.

Two flags drive the feature: `#auto-picture-in-picture-on-window-occluded`, which allows PiP to trigger when the browser window is covered, and `#browser-initiated-automatic-picture-in-picture`, which grants Chrome permission to enter PiP when those conditions are met.

A third flag, `#picture-in-picture-mute-control`, adds a mute and unmute button directly to the floating video window.

Limited Rollout

Still, the feature is not reliably available even for Canary users, who represent the earliest and most experimental stage of Chrome’s development pipeline.

Testing on Chrome Canary version 151 on both Windows 11 and macOS 26 confirmed that the `#browser-initiated-automatic-picture-in-picture` flag was absent from those builds entirely, making it impossible to activate the feature manually.

In a further inconsistency, all three required flags appeared in Chrome 149 — the current stable release — but enabling them produced no effect on tested machines.

That pattern points to Google running an A/B test, a controlled experiment in which only a subset of users receives a feature regardless of their build version, with access managed server-side rather than through a local software update.

Users who want to test the feature can open `chrome://flags` in either Canary or stable Chrome, search for the flags listed above, enable each one, and restart the browser.

Google has not announced a timeline for a broader rollout to the stable channel.

PiP mode has been available in Chrome as a manual option since 2018, letting users right-click a video to detach it into a floating window. The new behavior under test would make that transition automatic based on what happens at the operating system window level, removing the need for manual input.

Chrome Canary receives daily updates and routinely carries experimental features that may be altered, delayed, or dropped before reaching stable release.
