Resistance: Fall of Man [BCUS98107]

Some weird glitches in the later levels, getting these big white polygons covering the screen:






That white light on the floor is also part of the glitch.
Could be related to the fog. 

You can see how it looks in the original hardware at 3:57:00:



Some people reported that foliage is also missing and it could be related to this glitch, in bigger maps you can see foliage in the distance, so it looks like something related to draw distance, just throwing some ideas here. 

Tested on version: 0.0.13-11342-d1e78374 Alpha

Again hope this helps, sorry for the double post.
