The bug
Prior to this version, there was shading (if a bit overcompensating), but it seems completely absent on this snapshot.
It should be returned to its appearance pre-1.15 snapshots.

The blocks are still shaded, but the shadow is now on the right side of the blocks again and a lot lighter than it used to be.
@violine1101 Is that intentional? I know that you might not know at all.
I'm pretty sure it's not.

In 19w39a they are too dark and in 19w40a they are too bright. Maybe in 19w41a they'' be just right...

Fixed in 19w41a

Please resolve as Fixed.
This actually isn't fixed, the new shadows are just caused by MC-163242.
The inventory items are now rendered correctly. I assume that the fix for this issue caused MC-163242 though.

Now MC-163242 is fixed in 19w42a this issue is back.

The blocks are still too bright in 19w46b.

Please make Mojang Priority: Important, it looks worse than Bedrock Edition.

Absolutely agree, it would be essential that this bug be fixed before the release of the 1.15!

Glad to see this is finally fixed! It took a while, but I think it's fine now again.
