When automating browser interactions using Playwright in an Electron environment, a brief visual artifact occurs during page navigation. Specifically, after launching the browser via Playwright and performing a search on Google, clicking any link in the search results triggers a transient semi‑transparent mask/overlay. A small yellow block appears at the top‑center of this mask for a moment before the target page loads. This artifact is purely visual and does not affect functionality.

Environment:

• Playwright version: 1.57.0
• Electron version: 35.2.1
• Chromium version: 132.0.0.0 (local installation)
• Operating System: Windows 11
• Test scenario: Manual interaction within the launched browser (not headless)

Steps to Reproduce:

1. Launch Chromium via Playwright in an Electron context.
2. Navigate to https://www.google.com.
3. Perform any search (e.g., “test”).
4. Click any link in the search results.
5. Observe the brief appearance of a mask overlay with a small yellow block at the top‑center during the transition.

Expected behavior:
Page transitions should be smooth without any visual artifacts or unexpected overlay elements.

Actual behavior:
A mask‑like overlay with a yellow rectangular block appears for a split second when moving from the search results page to the target page.

Additional notes:

• The issue only occurs when the browser is launched through Playwright; manual browsing in the same Chromium version does not show the artifact.
• The artifact appears consistently on every search‑result link click.
• It may be related to Playwright’s injection of scripts, network interception, or rendering emulation during navigation phases in an Electron‑wrapped Chromium instance.
