It's some sort of backside culling that is unrelated to video card, at least that's Citan's best guess.

At least, I have it happen to me when I'm on the PC with the VR setup and the tiny Mac Air with the Intel integrated. I haven't had it happen in awhile.

If you can do anything to reduce your network load or background processes it seems to happen less; like there's some sort of timing issue and the game is busy changing out one part of memory while your character is still moving. That's what's helped for me.
