Chrome Version: (copy from chrome://version) 133.0.6943.128
OS: (e.g. Win10, MacOS 10.12, etc...) Win10

What steps will reproduce the problem?
(1) Unzip the attached sample folder. It contains some sample assets, a script "screenshot.js" to run Chrome and take screenshots, and a folder with successful and error screenshots.
(2) Add the full file-path where the ad is stored on line 76 of the script.
(3) Run the attached script which:
   - Opens browser via CDP.
   - Navigates to attached HTML.
   - Takes screenshots every 50ms.
   - Monitors for blank/small screenshots (<20KB)
(4) Observe that occasionally, screenshots return blank images.

What is the expected result?
The screenshot should always show what is visible on the screen.

What happens instead?
I intermittently get blank screenshots. Blank screenshots could be completely blank white images or almost blank images - a white image with only the AdChoices logo visible.

Additional Information
- We use Chrome to load certain ad URLs and take screenshots using Selenium WebDriver. Since the last few weeks, we have seen a rapid increase in the number of blank screenshots. Instead of a screenshot of the actual page, we see just a blank white image with just the AdChoices logo. I am able to reproduce this behavior locally both manually and using a script. This has been seen in versions 132.0.6834.160 and 133.0.6943.127.
