+# Omarchy Flickering — Intel Mac Mini (Continuous)
+
+Status: **Under investigation — continuous flicker reported by user (Alister) on Intel Mac mini (first thinner model) with Omarchy installed.** Not Apple Silicon (`apple-drm` / `simpledrm` race — see `omarchy-mac` commit `e06fa26`). Most likely cause: **hybrid graphics / external-monitor / compositor-level flicker** (Hyprland + Chrome/GPU + `apple-gmux` / i915 interaction), per Omarchy GitHub #2745 (NVIDIA flicker, GPU-accel-related) and #2800 (scaling-related screensaver flicker / focus race).
+
+Quick fixes to try (from verified issue reports):
+- `env LIBVA_DRIVER_NAME=iHD` (or `radeonsi` if AMD discrete) in `~/.config/hypr/envs.conf`; reboot.
+- Hybrid GPU: `/etc/modprobe.d/apple-gmux.conf` → `force_igd=y`; rebuild initramfs; reboot.
+- Chrome / Chromium flicker: disable GPU acceleration (`chrome://flags` or `--disable-gpu`); `--use-gl=desktop` removed (Chrome 149+); try `--use-angle=gl`.
+- External monitor: check gamma/display profile; confirm `i915` / `amdgpu` / `apple-dr` loads (`dmesg`).
+- Idle / screensaver: disable screensaver or adjust `GDK_SCALE` / `scaling` (#3924: 1.2 / 1.33 breaks; try 1.0 / 1.5 / 2.0 or disable).
+
+Not confirmed fixed — needs user testing. Log updated when outcome known.

+# 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).
