Hello liufankong

Thank you for reporting your experience in the Intel Communities. We see that you are experiencing a flickering problem when reproducing videos in a Chromium-based browser. We will be more than happy to help you. To better assist you, we would like to request some information about your issue:

• When did the issue start?
• You mentioned that it is only when using the Chromium browser. Did you confirm if the issue is present in non-chromium-based browsers, for example, Mozilla Firefox?
• Is the issue reproducible when playing videos on other applications? You can check using Windows Photos options.
• Is the problem related to the website you use? Or it can be replicated using other video streaming websites?
• We would like to have further information about your system to look into this problem internally, so please provide us with the Intel®️ System Support Utility (Intel®️ SSU)
  • Open the application and click "Scan" to see the system and device information. By default, Intel®️ SSU will take you to the "Summary View."
  • Click on the menu where it says: "Summary" to change it to "Detailed View."
  • To save your scan: click "Next"; then "Save."
