Im having the same issues, it happens on every version. i tried everything to fix it but nothing haves effect. im 100% sure its not my system drivers because i play minecraft since i got my pc and it hadnt problems.
i already seen a lot of broken world generator like: grass, tall grass and trees in air, water not flowing, sugar cane without water near, grass and tall grass in sand, etc...
I activated a beacon in Y=-62 and the light goes from -63 to 960
Ok so after hours it launches so it is not a bug, just my pc that takes too long lol
