Public bug reported:

Ubuntu 22.04 development branch on kernel 5.15.0-17-generic @  18/1/2022

Booting into desktop gets heavy screen flickering and disforming (unusable)
both booting on xorg and wayland

on kernel 5.13 it did not occur so heavy (only little glitches once in a
while see bug 1948778)

adding the kernel paramater intel_idle.max_cstate=4 fixed this

i had these same bugs on this machine before:
