The display on Lenovo Xiaoxin Pro 13 2019 (Lenovo XiaoXinPro-13API 2019) briefly shows a garbled screen upon wakeup from S3 with kernel v6.13.2, but not with v6.14-rc1. I have bisected to 04d6273faed083e619fc39a738ab0372b6a4db20 ("Revert "drm/amd/display: Fix green screen issue after suspend"") as the fix to this issue.
However, it is quite strange that the title indicated a revert to the fix for the exact issue I was experiencing - despite the commit claiming that the maintainers "cannot see the issue" any more. It seems that I'm running into some sort of unexpected issue that is outside of AMD's test case.
In any case, this commit fixes the issue on the device I have tested and applies cleanly on 6.13. I would therefore like to request for this commit to be backported to 6.13 (and maybe other branches, but I think the maintainers may have a better idea on this).
