>From diving into the upstream bug, these patches would be related: [PATCH 0/3] Fix some PSR/Replay stuttering issues [PATCH 1/3] drm/amd/display: Do not wait for PSR disable on vbl enable [PATCH 2/3] drm/amd/display: Do not elevate mem_type change to full update [PATCH 3/3] drm/amd/display: Disable replay and psr while VRR is enabled
These would be at least in 6.12.11 https://web.git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=v6.12.11 So that would likely mean they're in plucky (6.14 kernel) but I don't want traces of them in the changelogs of oracular, noble, or jammy HWE. ** Changed in: linux (Ubuntu) Status: Confirmed => Fix Released ** Also affects: linux (Ubuntu Oracular) Importance: Undecided Status: New ** Also affects: linux-hwe-6.8 (Ubuntu Oracular) Importance: Undecided Status: New ** No longer affects: linux-hwe-6.8 (Ubuntu Oracular) ** Changed in: linux (Ubuntu Oracular) Status: New => Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2092063 Title: Graphical corruption on Zen4/RDNA3 APU Status in Linux: New Status in linux package in Ubuntu: Fix Released Status in linux-hwe-6.8 package in Ubuntu: Confirmed Status in linux source package in Jammy: Won't Fix Status in linux-hwe-6.8 source package in Jammy: Confirmed Status in linux source package in Noble: Confirmed Status in linux source package in Oracular: Confirmed Bug description: Laptop: Lenovo Thinkpad Z13 Gen 2, 1920x1200 IPS 400 nit touch display, Ryzen Pro 7840U. OS: OEM Ubuntu 22.04 LTS in its default Lenovo configuration, with latest HWE kernel (https://launchpad.net/ubuntu/+source/linux/6.8.0-50.51) The corruption looks a bit like hardware/display/cable problem but is apparently a software one. See videos (especially https://gitlab.freedesktop.org/-/project/4522/uploads/3904f33b8366bfa94eba39e039c6d12f/output2.webm and https://gitlab.freedesktop.org/-/project/4522/uploads/64ec2cbd8b98806a3c94459d0453c484/VID_20240913_001050.mp4) in the upstream report. Latest kisak-mesa does not change symptoms in any way, but in the upstream report there are some kernel patches that could be tried out. For many amdgpu.dcdebugmask=0x10 does workaround but consumes a lot more battery. In my case I have not been able to test that yet since the laptop is not mine. This bug is to track upstream drm amd 3388 ticket https://gitlab.freedesktop.org/drm/amd/-/issues/3388 , with possible duplicate topic https://gitlab.freedesktop.org/mesa/mesa/-/issues/11216 so that the (potential) fixes from there eventually land to also Ubuntu 22.04 LTS HWE kernel.
