by ·

According to a support announcement issued by Intel, the company is aware of compatibility issues with Intel 12th Alder Lake CPUs with browsers such as Google Chrome and Microsoft Edge. The specific performance is that scrolling the web page with the mouse is stuck, and there is a delay of about 2 seconds when the mouse is clicked, which looks like the browser is stuck.

Hidden Chrome Features
Affected CPUs include 12900KS, 12900K, 12900, 12900E, 12900T, 12900TE, 12700K, 12700, 12700T, 12700E, 12700TE, 12600K, 12600, 12600T, 12500, 12500T, 12500E, 12500TE. You can go to Windows 10/11 Settings, System, About page to check your CPU model, if the model is in the list above, it means it is affected.

What these CPUs have in common is that they all use the Intel UHD Graphics 770, and the problem is caused by the driver released by Intel. Intel is currently working on a solution to this problem, and users can use the following methods for temporary processing before releasing the solution.

To resolve this issue, follow these steps:

  1. Update the browser to the latest version.
  2. Update Windows® to the latest version and run any pending updates.
  3. Try a Clean Installation of Intel® Graphics Drivers in Windows using the latest customized driver offered by the motherboard manufacturer (OEM) or using the Intel® generic drivers available on our Download Center.
  4. Disable Hardware Acceleration on the browser or switch from an HDD (mechanical Hard Disk Drive) to an SSD (Solid State Drive).
