Sporadic visual issues with NVidia GeForce RTX graphics cards

[Poobslag]

A user reported a random visual glitch in the middle of playing. They tabbed out to look for a screen shot, and went back and it looked like this.

The user has a NVIDIA GeForce RTX 2070.

Even if we can't fix the crashes, we can probably do something about the glitchy wallpaper appearance. The wallpaper shouldn't really require shaders or anything that clever. We implemented it 4 years ago, and it's possible if we try again we can think of a simpler or more clever way to implement it.
