i saw that people had this problem, many of them are using shaders, im not, when i enable them the problem fixes itself like the bot says, anyway.. I tried everyting ( 0.0, 1.0, 0.1-0.9, restarting the files 3 times, other version (1.21.10) ), its based on a specific Y level everything above me is glitched like on the photo.. I just dont know how to fix it
