Looks like something's gone wrong with your assets there. If that's still happening after a restart, try going to Options -> Report Bug -> Repair Game Files. That should fix it

Hi! We're noticing that there are unintentional effects with other plug-ins that affect graphics. Can you try to disable any plug-ins that effect graphics? I've noticed others saying that setting your fog depth to 0 on the GPU (experimental) plugin works too.
