In Minecraft Preview of the Bedrock edition, if you have the Darkness effect and the Night Vision effect, a half blue and green light appears. As you can see in the video, I really loved the new update of the Darkness effect with Night Vision, but it's still not perfect because a green light appears that interferes with the gameplay a little. The green light passes quickly so I left a video with Slowmotion for you to see better. Please fix it.
