It's not life-threatening problem but I'm just curious... I'm working on a really big map for a mod that's in developement. When I generate textures after I added some paths/roads/grass/etc and I wait while it does it's thing at 4000x I see the screen go white and then I see the foliage go pitch black and flicker from showing to not showing then back again. The textures come out just fine, but I was wondering why it flashes like that when I generate them. ??
