Some places produce illogical shadows:

Removed some screenshots that cannot be reproduced in 18w03b.

Affects 20w28a, requesting ownership

Walls, fences, glass, slabs and stairs don't seem to be affected anymore, but solid blocks, cobwebs, transparent blocks (such as the beacon, leaves (depending on your graphics) and the honey block seem to be affected) and also the blocks that emit light are. (As of 1.16.1/20w28a)

In 20w29a

I can no longer reproduce any of this in 1.17-pre2 except for the water issue.

I suspect it might have something to do with ambient occlusion.
