There is a glitch/bug in the current caves and cliffs beta program. Whenever I try to ride a minecart the first person view always gets stuck inside the cart and I am uanble to see the surroundings. Whenvere i try to change my camera direction to any other side this glitch is occuring and is flickering. I was not able to attach a screenshot of the glitch/bug as because the glitch was not stable because it was coming and going but still I will try my best to attach a screenshot with this report. And oh yeah I guess this glitch is fresh because I found this glitch yesterday night.
