Confirming a workaround that got it fixed for my HP ZBook Ultra G1a 14"
(Strix Halo / Radeon 8060S).

Workaround tested
- Previous cmdline already had: amdgpu.mes=0 amdgpu.dcdebugmask=0x10
- Changed to: amdgpu.dcdebugmask=0x410 (disable PSR + Panel Replay per @superm1)
- After update-grub + reboot: artifacts on the internal panel are gone (or no 
longer noticeable in normal use)

Additional info
- dmcub_fw_version before change: 0x09003f00
