Vibrant Visuals issue as of 26.21

Loading into my Minecraft survival world with Vibrant Visuals turned on produces a black box across the screen when trying to look around, but the world otherwise functions just fine with no lag. Turning Vibrant Visuals off returns visibility to gameplay, turning it back on produces the previous result. I am able to look down at the ground and regain visibility, but the black screen returns upon looking around the environment. Please see pictures for examples.
