Public bug reported: 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.
