I am having the same issue with a Lenovo Thinkpad X1 Carbon Gen 10 Model
21CBCTO1WW, CPU Intel i7-1270P with an Intel Iris Xe card.
I run Ubuntu 22.04.3 LTS and tested all the available kernels, including
the latest 6.7 mainline.
I also tried all possible combinations of the grub parameters in
/etc/default/grub...
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash 915.enable_psr2_sel_fetch=0
i915.enable_psr=0 i915.enable_fbc=0 i915.modset=0 intel_idle.max_cstate=2"
I tried with different distros (Fedora, latest Ubuntu, older Ubuntu)
with live USB-Stick.
The problem with the flickering persist on all the combinations on the internal
screen.
When I connect an external display via HDMI, the error persists on the internal
screen, but the external screen is stable and just fine.
I am starting to think that there might be an issue with the resolution
or the refresh rate of the internal screen.
Currently went back to the official 'linux-generic-hwe-22.04' which is a
6.5.0-14 Kernel

Bug description:
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 parameter i915.enable_dc=0 intel_idle.max_cstate=2
fixed this
i had these same bugs on this machine before:
