When smooth lighting is enabled, in a closed space with a width of 1 and a height of 2 facing north or south as shown in the figure, the shadow display is incorrect

You have to fix it,or Vibrant Visuals will have this problem too

It is very ugly when you are digging

It’s not only in 1×2 enclosed spaces—corners in caves and other locations have the same issue.（不只是在在宽度为 1、高度为 2 的封闭空间中，在矿洞等其他地方的角落也有。）

Yes,so it is a terrible bug.I wonder if mojang plays its own game. Such a bad and ugly bug has not been fixed for so long, or if mojang has never mined

Everywhere were broken and strange shadows

It is astonishing that it has existed for seven years, but no one pays attention. It is worth mentioning that both Optifine and Sodium in the community fixed this bug a long time ago

This is such a complex issue that it's hard for me to describe it precisely. Anyway, I hope they can notice this problem and fix it as soon as possible

Please fix it quickly. I can't stand such ugly smooth light shadows
