Linux users have reported seeing weird white flashes and rapid blinking on their Intel laptop displays after upgrading to Linux kernel version 5.19.12, leading to warnings that the bug may damage displays.
Besides being a visual annoyance, the unexpected screen flickering prevents users from doing anything on their systems, and Intel Linux kernel engineer Ville Syrjäl warns that it could also damage the display.
Syrjä recommended immediate reversion of the Linux Kernel to an older version to avoid causing hardware damage on people's machines and to publish a recommendation that "No one using laptops with Intel GPUs run 5.19.2".
This realization came after many users had already upgraded to the buggy Linux version, risking damage to their systems and becoming forced to apply kernel version downgrades.
Given the delay in pushing Linux kernel upgrades on many other distributions, the buggy version might land on some of them later.
Users are advised to check the kernel version numbers before upgrading and avoid Linux 5.19.12 if they're using an Intel laptop.
