1. Place yourself nearby some bamboo. (e. g. Altis 217144)
2. Optionally place another player behind it.
3. Look at the bamboo and walk away from it or approach it and notice that the bamboo will disappaer at a certain distance and reapper when in- or decreasing your distance more to it.

4. You will see other players through the invisible bamboo on the stage in question.

I have seen this for other bushes, too. E. g. the bush on the right of the bamboo in the "approach-3.png" screenshot shows same behaviour.
