The format of your buglink is incorrect and leads to a "Lost something?" page in launchpad.. I fixed it when applying, but please use the https://bugs.launchpad.net/bugs/<number> format in the fugure. Applied to eoan/master-next and unstable/master, thanks!

BugLink: https://bugs.launchpad.net/ubuntu/bug/1840236 [Impact] On IceLake platforms there might be a thin, horizon strap of corruption image at the top of screen randomly after some series of window operations and disappears within a second or so. This is found on multiple platforms and is quite annonying that results in bad user experience. [Fix] The upstream bug has been filed for previous platforms, e.g. GeminiLake for an year or so, still working in progress, and so far this only known work-around is to turn off framebuffer compression on affected platforms. [Test Case] The most easy way is to observe if such corruption appears during the transition from GDM to gnome-shell. Verified on pre-launch ICL platforms. [Regression Risk] Low. The work-around for GeminiLake was landed to Linux stable 4.14.125 and has been backported to B/D.
