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
