Reposting this from bug 1970426: 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.
