Bug with rendering on LAKE (Counter-Strike: Global Offensive)

Hi! Faced with such a bug https://vk.com/video169521855_456239388
As you can see, on the left and on the right wall, missing lifebuoys, and at the top there are no railings! I'm wondering is I have one. And this game is no exception. GTA 5 is connected to the traffic face. In PUBG about the same. In COP there is, that the textures flicker. Har-Ki PC: 1070 GTX TI, I7-3970X 3.5 GHz, 16 GB of RAM. I hope I'm not the only one
