The bug
The enchantment glint does not render properly on shields that have a banner applied to them. The enchantment only shows correctly on the handle of the shield.

Can confirm. This only applies to shields with banners, regular shields are not affected. I updated the ticket accordingly.

Can confirm this bug persists even in the release of 1.15
This bug still is in the release of 1.15 still.
It is also in 1.15.1
Fixed in 20w12a
Still happening for me in 20w12a. Note that this issue only affects shields with banners, not shields without them.

Hoping to see this bug fixed alongside armor not rendering enchanted. It's about time this get fixed.
It should be changed to affects shields in general as since 20w18a, my enchanted shield with no banner design doesn't look enchanted at all.
Confirmed in 20w19a. Normal shields render but banner shields do not. Perhaps make it render not on the banner but on the rest of the shield? (back of the shield and the metal edges if possible.)
I saw this bug too (in pre-release 4)
