here is the TLDR:
"AMD kernel developer wants to classify this is as both SDDM bug and plymouth bug https://gitlab.freedesktop.org/drm/amd/-/issues/3341. amdgpu kernel driver is not ready by the time that sddm and plymouth are started in some cases (race condition). Marking this as a sddm and plymouth bug (in addition to linux) because of this.

To me it seems that at least a systemd service should be handling blocking starting GUI userspace services until the kernel drivers are actually loaded but that is just my thought. I guess the AMD developer sees this the same way you do Daniel."
