Light flickering and shadow desynchronisation

Hi! I’m making a FNAF fangame and I’ve come across an issue where suddenly the lights start to flicker. The scene becomes overexposed, but the actual light source itself does not flicker and is not overexposed. This problem occurs only when looking at the scene from a very specific angle. Additionally, the issue appears only when the scalability setting is set to ‘Epic’ or higher.

Moreover, the scene seems to be split: there’s an unlit version and another, slightly shifted or stretched, where the scene is correctly lit.

Thank you for any advice!




(EDIT:)
I’ve figured it out: it was due to the fact that I’m using Raytraced Shadow and that my light souce was set to ‘movable’. By setting it to ‘static’ there was no more strange glitching. But the flashlight for my character has to be set to ‘movable’… Any idea?
