[MC-48778] Black squares in the sky

The sky has a big black squares near the horizon, which seemed to get bigger as the sun went down. Screenshots follow

EDIT: after I restarted, they were gone

EDIT 2: Only happens with shaders on, turning them off fixes it (tested with fxaa.json). The clouds and water are also darker

Cannot reproduce

Updating java didn't resolve the issue, and it only happens with shaders on. Tested with fxaa.json

Okay, confirmed for the black "square" in the sky with certain shaders

And also affected water

Everything is confirmed

Small points were fixed after updating java

You should delete the part that talks about points then.
