Rendering Issue while facing north-west

(Sorry for (maybe) bad English)
Founded something strange:

While standing between 2 chunks, looking in north direction and slowly turning to the west - chunk behind me isn`t rendered...
Even though, it can show entities (such as mobs, particles, etc.)

This issue is only on north-west side, not on others...

Tested on 1.15.2, 20w09a
