Looks like some of the textures have gone AWOL. I think there's an option in LFS somewhere to like 'refresh' the graphics or something? I'm not sure. Don't even have it installed so can't check unfortunately. I've seen the issue before but can't remember what needed to be done to fix it.
Try changing some graphics settings and if that doesn't work then download LFS again and try it on a new install.
I thought about textures but its rather imposible. Thats quite strange... Only GPU and drivers was changed. LFS was untouched for a lot of time... Maybe it is something with DirectX (but I reinstalled it too).
