I was making a modpack and I noticed there was a black wall sounding the edges of the chunks so I went through and disabled every mod until I got to reskillable which was the last mod I thought was causing it so I only loaded reskillable and jei and the problem still occurred I tried resetting all the settings to default and changing the render distance and going out of full screen but the void still persisted

I just deleted the profile and readded the mods and it stopped for some reason
