Chrome engineers have fixed a small but annoying visual bug that affected Picture-in-Picture (PiP) windows on macOS 26 (Tahoe). The issue caused a faint “ghost” title bar to appear above PiP windows, breaking their clean, frameless look. The fix landed on November 4 in Chromium’s main branch.
What changed
The Chromium team changed how PiP windows behave on macOS. Chrome now hides the default system title bar and relies only on its own PiP controls. This prevents macOS from drawing an extra title layer over the video window.
When you open a PiP window after updating, you’ll see a clean floating video without that unwanted title strip.
How it works:
The change updates a file in Chromium’s macOS code, BrowserNativeWidgetMac. It now marks PiP windows as frameless and sets a flag that hides the system title. This makes Chrome handle its own window design completely.
On macOS 26 (Tahoe), PiP could show a faint, out-of-place title band (“ghost title”) above the intended PiP UI. The fix aligns what users see with what Chromium intends: a clean, floating PiP window with Chromium-drawn controls only.
When will you get it?
The change was submitted by Google engineer Benjamin Keen on November 4, 2025, and merged into Chromium’s main branch. You’ll get it soon in Chrome Canary and then in future stable releases.
If you use Chrome on macOS 26 and saw a thin gray strip above your PiP window, this update removes it for good.
How to spot the original bug (pre-fix)
You can reproduce the legacy behavior (on an unfixed build) with a public Document PiP demo:
- Open the demo page.
- Click Open PiP to pop content into a floating window.
- On affected macOS 26 builds, you’d see a thin title sliver above the PiP content.
Bottom line
If your PiP windows on macOS 26 showed a weird extra title sliver, this Chromium patch removes it by hiding the OS title bar and letting Chromium’s own PiP UI take full control. Expect it to appear first in Chrome Canary and then trickle down the channels after standard promotion.
