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.
