See video attached. At 21 seconds on the video is where it is most clear: While sitting and drinking at a water truck, I used freelook. As I turned to the right, the group of buildings next to me disappeared completely for a split second, then reappeared. This behavior happened with a few other buildings as you can see in the video as well, but at 21 seconds on the video is where it is most apparent.
Reproduction steps
Drink from the water truck that spawns at Bar Kalay and use free look and look around left and right
