I did the following changes and am now flicker-free for two days:
In file /etc/default/grub I added to parameter GRUB_CMDLINE_LINUX_DEFAULT: i915.enable_dc=0 intel_idle.max_cstate=2
then: sudo update-grub reboot
I will report in a week if this indeed fixes the flickering or if it just happens less often. I never had night-light enabled.
