  • Rapid flashing may cause discomfort or seizures in sensitive people — stop immediately if unwell.

Photosensitivity & eye safety

  • This is not “dead pixel repair”. True dead pixels usually cannot be fixed by a webpage.
  • Stop immediately if you feel unwell. Escape always stops the cycle.
  • Default is a small region — not full-screen auto-run.

  2. Choose a small area and conservative speed first.
  3. Start only when ready; Escape or Stop ends the cycle immediately.
  4. Self-report outcomes locally — no repair guarantee.
