+# 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.
