I also have this issue on a Thinkpad T14s, AMD Ryzen 7 PRO 4750U. The issue is not present with kernels 5.9.10 or 5.15.23. It is present with the default kernel from the most recent KDE Neon (5.13).
Here's a short video, it's the same pattern (static and vertical lines on the right) as the other video in this thread: https://twitter.com/tlhunter/status/1493107390731874305 The pattern is reminiscent to an HDMI desync issue but the vertical lines do make it distinct. It appeared to affect the laptop screen but not an external display. The static appeared after the screen went to sleep and woke back up, though I don't believe the system went to sleep. -- 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/1958591 Title: [amdgpu] Random noise 'static' display after internal display turned off/on Status in linux-hwe-5.13 package in Ubuntu: Confirmed Bug description: Laptop internal display shows random looking 'static' after it's turned off and then on again. e.g. on suspend/resume, or when plugging/unplugging an external monitor. This appeared to come after a `dist-upgrade` took the kernel from 5.11.0-44 to 5.13.0-25 (hwe). Others are seeing this with both NVidia and AMD graphics hardware: - https://www.reddit.com/r/Ubuntu/comments/s8c83w/laptop_shows_static_screen_after_going_into_lock/ - https://www.reddit.com/r/Ubuntu/comments/s8fit0/please_help_static_noise_display_on_ubuntu_2004/ I use i3 under gnome-flashback, but tried using default Ubuntu/Gnome both X and Wayland, and gnome-flashback/metacity. All showed the same problem. Also tried an `apt install --reinstall xserver-xorg-video-radeon libdrm-radeon1` for luck - no joy. Running a 20.04.3 live stick the problem does *not* occur.
