This is a duplicate to https://bugs.freedesktop.org/show_bug.cgi?id=108085 that happens on IceLake platform as well.
It can be reproduced on linux v5.3-rc6 today, with the reproduce steps listed in bug 108085, but one can easily found a horizontal line of corruption at the top of the screen when logging in from gdm.
Blacklist IceLake as https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=396dd8143bdd94bd1c358a228a631c8c895a1126 did for GeminiLake is a known work-around so far.

Accordingly, all the above details are set.
@Maarten, Is this issue related to Bug 111484? Since you investigated Bug 111484 any suggestions here?
You mean Lakshmi if 103167 is same?

Sorry, yes it's Bug 103167 .
Likely identical, especially if disabling fbc from command line works.
marking this as dup. WIP on that has been already a while to understand cause of it.

Reporter, please also try as suggested using i915.enable_fbc=0 if issue still exists.
Ah, so suggested workaround using i915.enable_fbc=0 also works?
Yes, basically whatever turns off fbc would work. Thank you.
