While playing the new 1.17, the second I load into the start screen random visual glichs start happening. It looks like when someone  cracks a TV screen and it's has random black that fashes and colors. I have already tested out my computer and know that is not the issue, it has something to do with the 1.17 version, I have also loaded up the older versions of minecraft and this visual glich does not happen in any of those.
