Enabling shaders makes my whole world white and laggy

( for context i use the Essential mod for minecraft ) so basically whenever im in a world and i go to the in game iris shader menu and enable any shader it makes my world completely white and laggy with this kinda smudge like texture when i look around, and when i disable shaders everything goes back to normal. Ive been tweaking my mods by uninstalling some and testing my game to see if maybe its a mod I have but nothing is working
