Random Massive Lighting Issues

[Chloranthy]

On and off I've had huge flickering problems in the menu when starting up the game, and in the character select screen the lighting is also massively mangled, split into very clear bars of different shades. If I dare select a character and then start, most of the ground in-game will be textureless and black, and the horrible lighting split will persist. Every menu with any amount of light will also remain in a state of seizure-inducing flickering. I have not found a way to fix this. I have relaunched the game, verified files, restarted my PC, nothing works, and then the problem will suddenly solve itself one launch without explanation, even if I didn't do anything and simply relaunched the game for the seventh time about an hour after the problem started. Is there any concrete way to actually fix this?

Okay, deleting my shader.cache and making the game recompile them fixed it for now, I guess that's what I'll do from now on, just a bit annoying. If anyone knows of a more permanent fix, I'd be very happy if you shared it.

This has happened twice more so far, so I really hope someone knows a more permanent way to fix it or the game drops an update fixing it themselves soon.
