Vibrant Visuals Mali Gpu glitch

Hi, I am a Minecraft player from Asia Bangladesh. I am playing Minecraft from 2019. Yesterday I saw that the summer drop is available in beta/preview versions. I downloaded it and created a world as I turned on vibrant visuals the screen gets white as I move again the screen gets fully white. Then I opened youtube for the solution. Then one man like me has the same problem. In the comments some guys were saying that turning the volumatic fog can fix this. I did that then it actually happend. Then when I started moving again it glitches like it was in 15 to 24 fps but it was like its laging and glitching. My mother’s phone is 1 years old Samsung Galaxy A15 4G. I wish that the devolopers will fix this problem and give us the pleasure of playing minecraft in a great view. Thanks a lot.
