Thanks for the bug report.

Please try adding i915.enable_psr=0 to your kernel parameters (GRUB_CMDLINE_LINUX_DEFAULT) in /etc/default/grub and then run:

  sudo update-grub

and reboot.

Please tell us if that has fixed the problem, but regardless please also then run:

  journalctl -b0 > journal.txt

and attach the resulting text file here.

After a little use of my laptop, I moderate my first impression, I
notice less flash and blinking

Cheers.
