How to Fix Flashing Effects That Risk Photosensitive Seizures

Flashing that crosses the three-per-second threshold can cause real harm. Capping rate and area fixes it. Here is how.

How to fix it

1. Limit flash frequency

Cap any repeated full-screen or large-area flashing to no more than three flashes per second, the threshold used by photosensitivity guidance like ITC tooling.

2. Reduce area and luminance

Shrink the screen fraction affected and lower peak brightness for repeated flashes; localized, dimmer effects are far safer than full-screen white strobes.

3. Add a safe mode

Provide a photosensitive-safe toggle that replaces strobes with steady or slow effects and warn players at first launch if your game contains intense flashing.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
