The one you have is due to barb wire, this artifacting is new in this patch and occurs around military areas, it's much more intense than the barb wire one.

This patch is giving me a CTD just after receiving mission data, I've tried all of the OA Betas, I've uninstalled OA and re-installed it, I've even tried SixLauncher. Loading the armory or scenarios work fine, just joining servers doesn't work.
