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 Source: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2148088 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2154424 Title: eDP CRT-like tearing on HP ZBook Ultra G1a (Strix Halo 8060S), amdgpu, Wayland To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2154424/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
