This happens to my machine as well. The flickering appears to only
happens at the left-hand side of the screen or at the bottom of the
screen. I don't think I've ever seen the whole screen flicker or on
other areas of the screen except on the one I've mentioned.
I've tried most of the suggestions here and online by changing the
kernel parameters but to no avail.
Currently, I have `i915.enable_psr=0` set up but that only appears to
reduce the symptoms not fixing the problem completely.
