The file 32e29362-751d-4df0-99bb-9b2150ac111b.mp4 (shortened to in some contexts) demonstrates a visual bug in Godot 4.1.1. The issue occurs when the camera is at specific angles relative to positional light sources, causing the engine to select the incorrect quadrant for shadow maps, resulting in flickering or disappearing shadows. Key Discussion Points for a "Piece"
: Describe the visual artifact where shadows fail to render correctly even though the light source is in view. Explain the "perpendicular provocation," where the bug is most likely to trigger when the camera is perpendicular to the light source. 29362.mp4

If you are writing an article or technical script about this, consider these segments: Explain the "perpendicular provocation," where the bug is
: According to community findings on GitHub , users can mitigate this by manually setting the shadow atlas quadrant subdivisions to a consistent value (e.g., 4) in all quadrants, which forces the engine to avoid the faulty dynamic switching logic.
