--- Comment #44 from Mark Spencer <n7u4722r35 at ynzlx.anonbox.net> ---
This bug is strictly connected to i915.enable_psr=1 setting and it dates back
to 4.6 kernel when it was enabled by default for BDW. See:
https://bugs.freedesktop.org/show_bug.cgi?id=95176
For example here is report which connects flickering with 40hz refresh rate,
same thing which you asked me before:
https://bugs.freedesktop.org/show_bug.cgi?id=95176#c26
It affected different machines and it's probably fixed for some of them.
This bug report and https://bugs.freedesktop.org/show_bug.cgi?id=97918 are
about similar problem specific to Hp spectre x360 machine (could be connected
to others but who knows).
There are no such issues with i915.enable_psr=0.
