Visible flying blocks (above 240) outside of view distance if flying above 256
Blocks of the world will be rendered inside the view-distance-border-region (one chunk wide) when:
1. Blocks are built above Y=240
2. The Viewport (Eye-Height) of the player is above 256
This only happens (in singleplayer) if the blocks area inside the 1-chunk border that is loaded but not visible.
The attached screenshots show this problem.
First screenshot:
- The blocks are within the set view distance and everything is visible as expected
Second screenshot:
- The blocks below 240 are unloaded as expected
- The blocks above 240 are still visible outside of the set view distance
The problem exists in 1.15.1 singleplayer and 1.15.1 server. Setting the worldtime to /time set 13000 helps spotting these problems.
