Screen Flickering on Fedora 35 After Linux Kernel 5.19.12 Upgrade and Intel's Fix
Users of Fedora 35 reported severe screen flickering after upgrading to Linux kernel 5.19.12‑100.fc35, a problem not seen in the previous 5.19.11‑100.fc35 kernel, which Intel engineers identified as a potential LCD power‑sequencing delay and fixed in kernel 5.19.13.
Several Fedora 35 (Workstation Edition) users, including one with an Intel i7‑1065G7 CPU, experienced rapid white screen flickering after upgrading the Linux kernel to 5.19.12-100.fc35 . The issue did not occur with the earlier kernel 5.19.11-100.fc35 .
One user described the display behavior as resembling "90s party lights" after selecting the new kernel from the GRUB menu. Another Fedora 35 user reported similar flickering even in UEFI mode, noting that the high frequency made it impossible to capture on video, and initially blamed hardware rather than the OS.
Reports also came from Arch Linux users encountering the same symptom.
Intel engineers, after reviewing kernel logs provided by the users, identified a "potential screen power‑sequencing delay" in Linux 5.19.12 that could permanently damage LCD panels. They issued an urgent fix and recommended upgrading to Linux kernel 5.19.13, as announced on the Linux kernel mailing list.
