It also didn't work with this patch. You mentioned 32 bits per pixel, so
I tried switching video modes and it turned out the terrain was drawn
correctly when I changed from 24 bit mode (maximum with nvidia drivers)
to 16 bit mode and also when I changed the resolution in 24 bit mode
from 1024x768 to 800x600 or 640x480. Also, in 16 bit mode the "high CPU
load" problem disappeared.
