I am seeing this static since kernel 5.13.0-28 and even now after today's update to kernel 5.13.0-35 the static still appears for a while while rebooting / shutdown.
The issue is same, "Laptop internal display shows random looking 'static' after it's turned off" This is xubuntu 20.04 running on ASUS Laptop with AMD Ryzen 7 3750H with Radeon Vega Mobile Gfx -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.13 in Ubuntu. https://bugs.launchpad.net/bugs/1958523 Title: [amdgpu] Static-noise-like effect Status in linux-hwe-5.13 package in Ubuntu: Confirmed Bug description: Hello, I have encountered a bug in Ubuntu. When I turn on my laptop and log in (I can see the login screen) I see static-noise-like effect. I was able to make a screenshot and it depicts my desktop as if the problem didn't exist. Switching to stable (non-HWE) kernel solves the issue. My desktop environment is GNOME.
