Dead by Daylight dev warns of photosensitivity issues due to flashing lights bug

While the latest Dead by Daylight 7.7.0 update brought many good adjustments, balances and bug fixes, it has also inadvertently introduced a flashing lights bug that could potentially be dangerous to people with photosensitivity.

Why does the flashing lights bug happen in Dead by Daylight?

Currently, there are no exact triggers for the flashing lights bug in Dead by Daylight. Behaviour has stated that the bug seems to occur randomly in trials, and not everyone experiences it.

In the last few matches that I played, I didn't see it once. However, many have already experienced it. Players report that they have had the issue after being hooked, in the basement, and even on the post-game screen. Until the developers figure out the exact cause of this issue, be cautious when playing Dead by Daylight.

The bug is described as strobing and flashing lights that can cause discomfort. While there are items that include blinding lights, such as flashlights and firecrackers, this is taken to the extreme. If you have photosensitivity, an epileptic condition, or have experienced seizures, then be careful, as this bug could be very dangerous to you. The smartest thing to do is avoid the game until DBD announces that it has been fixed. It's better not to risk it. You can keep up to date with their progress on resolving the issue on the official Dead by Daylight X (formerly Twitter) account.

Behaviour Interactive has made sure that everyone is aware that this flashing bug is currently happening. They have posted about it on all of their social media, including Reddit, and have even added a warning once you load into the game. They also warn the community to refrain from posting videos of the strobing lights bug and to turn off autoplay on social media in case someone does post a clip.

Some speculate that the bug was caused by the switch from Unreal Engine 4 to Unreal Engine 5, which runs a different lighting system. Whatever the case, hopefully, Dead by Daylight will fix it soon so that all players can return to the game safely.
