Player is lighted incorrectly in creative menu and when recipe book is open

Noticed this same bug as well. Pretty sure it affects all instances of seeing the player in the inventory and not just when in creative or in the recipe book.

Still present in 1.15 Pre-release 4

Does MC-165183 describe the issue?

Still present in 1.15 Pre-Release 5. The bug that was resolved is not the same as this. This one is just some shading differences on the various sides of the player model. I'd say a little brighter than they were in 1.14.4.

What exactly is incorrect about it?

Well it's fixed now so this ticket can be closed.

Closing as Cannot Reproduce then.
