rendering is buggy in distancedistance and at map start

Happens in both gamemodes, no specific difficulty in reproducing! Just launch a map.

Map ought to render smoothly.

Bizzare holes temporarily appear in world during first minute or so of play.

Throughout the whole play time the distance will sort of strobe light and dark at the edges of blocks. The closer you get the less it does it. Turn render distance to medium low for most reliable reproduction.
