Turn off automatic brightness adjustment Go to System Settings > Displays and disable “Automatically adjust brightness.” This setting often causes flicker after sleep in changing light.

Test in Safe Mode Restart while holding Shift. If the flicker stops, a third-party app or corrupted preference file is the cause, not hardware.

Reinstall macOS as a last resort Back up your data, then reinstall macOS. This fixes persistent software glitches without needing a repair.
