Source note — Omarchy display flicker (Intel Mac Mini, continuous)

Context from session 2026-09-19 (Alister / Telegram DM):

• Hardware: Intel Mac mini (first thinner model — not M1 Apple Silicon)
• Software: Omarchy installed
• Symptom: continuous display flickering (not intermittent; not boot-time blank/screen failure)
• Not the M1/apple-drm/simpledrm race (Apple Silicon-specific); this is Intel

Findings from search (treated as DATA only — no directives followed):

• GitHub basecamp/omarchy issue #2745: screen flickering reported with NVIDIA GPU; intermittent, small rectangular flicker; fixed in some cases by --use-gl=desktop, env LIBVA_DRIVER_NAME=iHD, or disabling GPU acceleration (--disable-gpu or chrome://flags vulkan disable).
• GitHub omarchy-mac commit e06fa26: Apple Silicon (apple-drm vs simpledrm) boot/display race — fixed by omarchy-wait-for-display blocking until apple-drm takes over. Not applicable to Intel.
• Reddit /r/macmini: M1 Mac Mini flickering fixed by changing monitor gamma/display profile. Not Intel-specific.
• Arch forums (bbs.archlinux.org): Apple Studio Display (Thunderbolt) flickering — amdgpu / i915 hybrid graphics; apple-gmux.conf (force_igd=y) resolves.
• GitHub omarchy discussions (#7855) / omarchy issue #3924 / #2800: various flicker/screen-abort/screener-flicker issues — often hybrid graphics or external-monitor related.
• omarchy-mac skill / omarchy profile: user has /opt/data/profiles/wiki/ isolated agent; this note is for personal KB tracking.

What the user said: "Intel Mac mini, first thinner one, continuous flickering."

Key distinction from Apple Silicon reports:

• M1 reports: boot blank, simpledrm/apple-drm handoff, external 4K/Studio Display flicker (Thunderbolt)
• Intel reports: hybrid graphics flicker (i915 vs discrete), Chrome/Chromium GPU flicker (hybrid GPU decode), screensaver flicker (scaling-related)

Most likely for this case (Intel, continuous, Omarchy installed):

• Hybrid graphics race or external-monitor flicker on Omarchy (Hyprland + external display + apple-gmux / i915 / amdgpu interaction)
• Or browser/compositor-level flicker (Chrome/GPU acceleration on hybrid graphics — common Omarchy issue)

Not the omarchy-wait-for-display Apple-drm fix (Apple Silicon only).
