Minecraft 1.16 creates stripes and triangles (probably z-fighting)

When I go onto minecraft 1.16, Everything (especially clouds and maps) makes these weird stripes and triangles. I've tried restarting my computer. I don't have any plugins or mods. It seems to be more broken the further away you are from blocks, to the point where entire walls are invisible.

This seems to be what's causing it: https://en.wikipedia.org/wiki/Z-fighting

 

No, this isn't a duplicate! It is a completely different bug.
