Intel Linux laptop users on Linux 5.19.12 have begun reporting "white flashing" display issues with one user describing it as "[the] laptop display starts to blink like lights in a 90's rave party."
Intel Linux kernel engineer Ville Syrjäl posted today on the kernel mailing list:
After looking at some logs we do end up with potentially bogus panel power sequencing delays, which may harm the LCD panel.
Greg, I recommend immediate revert of this stuff, and new stable release ASAP. Plus a recommendation that no one using laptops with Intel GPUs run 5.19.12.
Greg Kroah-Hartman has immediately released Linux 5.19.13 with the problematic Intel graphics driver patches reverted.
Greg commented, " This release is to resolve a regression on some Intel graphics systems that had problems with 5.19.12. If you do not have this problem with 5.19.12, there is no need to upgrade. "
