--- Comment #35 from Mark Spencer <n7u4722r35 at ynzlx.anonbox.net> ---
It's strange thing but it looks that I can't reproduce flickering with kernel
4.9.21 anymore. It occurred for sure with 4.9.13. I see there was a patch
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/diff/drivers/gpu/drm/i915/intel_opregion.c?id=v4.9.13&id2=v4.9.22 

Anyone can confirm this?
