Point Light Optimization Causes Delayed Lighting and Missing Light Sources

In Minecraft Bedrock Beta 1.26.0.27, the recent optimization applied to point lights causes several visual issues when multiple light sources are placed close together. When many point light sources are nearby, some lights stop rendering entirely, and newly placed light sources do not appear instantly. Instead, there is a noticeable delay before the point light becomes visible. This behavior makes lighting feel inconsistent and unstable. This optimization negatively affects visual clarity and immersion, especially in enclosed environments such as caves, corridors, and interiors. The sudden disappearance of point lights or delayed loading gives the impression of a rendering bug rather than a smooth performance optimization. Instead of abruptly disabling point lights, a better approach could be: Dynamic prioritization of nearby light sources Smooth fade-in transitions for newly placed lights A graphics or performance option that allows players to scale point light intensity or limit the number of active point lights This would preserve visual consistency while still maintaining performance on lower-end devices.

    I'm having the exact same issue on Xbox Series X in Preview build 26.50.22 with the unified Block Light Quality setting. This lighting/shadow bug is not new for me. I have been experiencing this issue for quite a while now on past builds as well.

    Behavior: When set to Point Lights++ (or other level of Point Lights), block-based dynamic shadows stutter heavily (lowering shadow frame rate update) upon reloading a world, because for the first time with this build, when I create a new world just after the update, I don't have any issue. The bug comes after the reloading.

    Troubleshooting tested: Lowering all other graphics settings to the absolute minimum, fully restarting the game and the console, and toggling the settings back and forth did not fix the issue at all. The stuttering persists systematically upon entering the world.
