ProbeLabs65 findings · 95 requirements

A proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

Original report

Stable mirror contains broken linux-firmware-amdgpu 20260810-1revision 1 · captured 2026-10-04 12:03 UTC via poll

System details

What's wrong?

Stable mirror contains broken linux-firmware-amdgpu 20260810-1

After a recent update I noticed colour corruption on some higher-resolution AV1 videos in both Firefox and Chromium on an AMD RX 9070 XT.

The issue appears as rectangular sections of the video displaying incorrect colours. Lower-resolution streams, such as 480p, appear unaffected.

After some investigation, this appears to match an upstream regression in:

linux-firmware-amdgpu 20260810-1

My system is currently using the Omarchy stable mirror:

Server = https://stable-mirror.omarchy.org/$repo/os/$arch

and it currently provides:

Repository : core
Version    : 20260810-1

Arch has since released 20260810-2, which appears to fix the AV1 corruption reported by other AMD users.

For comparison, the repository metadata currently reports:

Omarchy stable core.db
last-modified: Fri, 14 Aug 2026 15:15:59 GMT

Omarchy edge core.db
last-modified: Tue, 18 Aug 2026 18:28:39 GMT

I appreciate that holding packages back is intentional for the stable mirror. I'm raising this because it looks like the stable snapshot happened to capture the broken firmware shortly before the upstream fix became available.

Would it be worth bumping linux-firmware-amdgpu to 20260810-2 on the stable mirror?

Additional testing

  • GPU: AMD Radeon RX 9070 XT
  • Mesa: 26.1.7-1
  • libva: 2.24.1-1
  • Reproduced in both Firefox and Chromium
  • Affected 4K stream: av01.0.12M.08
  • Unaffected 480p stream: av01.0.04M.08
  • Disabling Firefox hardware video decoding did not resolve the issue
  • The corruption is visible in screenshots, not just on the physical display
