Bug #4219

Disruptive and Bright Light Phenomenon in Trial

Status:	Open
Priority:	Critical
Added by:	Yimmi on June 16, '26
Assigned to:	Unassigned
Due date:
Reported for:	10.0.0
Actual Result:	Blinding light that is present during majority of the match that makes survivor gameplay especially difficult and not fun to play.
Expected Result:	Clear gameplay with no harmful or distracting disruptions.
Severity:	Major
Reproducibility:	Always
Platform:	Steam
Additional Notes & Comments:	This is the same bug that has existed since the patch in April, the one that had the hotfix GPU test branches. Those test branches lessened the issues though they were still present a little. I was really hoping that this would be fixed with Jason's chapter release, I'm disappointed that is not the case. I had a thought it's AMD specific, but I've seen forum posts and other posts claiming it did/does exist for NVIDIA as well. Attached with the current log files are a backup that was from a previous patch, for comparison if that helps.

Steps to Reproduce

1. Open dbd
2. Queue survivor or killer
3. Load into the trial
4. Move around
5. Move camera around
6. Change elevation on the trial map

Explanation

When in a trial, a blindingly bright green light appears at the top left of the screen. Said light changes in size and brightness randomly throughout the match, and is almost always present.

For survivor POV, it can range from being very small to taking up majority of the upper left corner. It seems to have a "following" behavior as it leaves a trail behind it when moving. It is very disruptive, often making seeing objectives and the killer extremely difficult. It makes looping basically impossible if it happens to be present, as it covers part of the screen. It is also very harmful to the eyes with its level of brightness.

For killer POV, it isn't nearly as bright or big, but it is still present, in the top left corner of the POV.

The lights size and brightness seems to react to elevation within the trial, such as going up sloped terrain or buildings, getting brighter and bigger randomly. It also seems to change depending on certain lighting sources like lamps, the sky, among others. On a less important note, it seems to sometimes randomly change to blue, sometimes purple.
