Thanks. For each "KMS update failed: drmModeAtomicCommit: Invalid argument", the only unusual things I can see are:

KMS: [atomic] Setting CRTC (83, /dev/dri/card1) gamma, size: 4096
KMS: [atomic] Setting CRTC 83 (/dev/dri/card1) property 'GAMMA_LUT' (28) to 161

which means either Night Light or a custom colour profile is enabled on the AMD GPU.

This is a problem I've seen before in bug 1968040 but the same "Invalid argument" can have multiple causes and "gamma" is just one that I've seen.

Since we can't reproduce the issue in development at the moment, and therefore can't debug it, I suggest sticking to the workaround:

  MUTTER_DEBUG_FORCE_KMS_MODE=simple
