The bug
If a texture file for an inventory screen is given translucent pixels, those pixels will render completely opaque in-game.
This was not the case prior to release 1.15 for many screens.
Affected screens
Everything located in textures/gui/container (excluding gamemode_switcher.png) is affected by this issue:
Anvils
Beacons
Furnaces, blast furnaces and smokers
Brewing stands
Cartography tables
Crafters
Crafting tables
Dispensers and droppers
Enchanting tables
Chests (both sizes), trapped chests (both sizes), ender chests, minecarts with chests, barrels
Grindstones
Hoppers and minecarts with hoppers
Horses, donkeys, mules, llamas, trader llamas and camels
The Survival inventory screen
Looms
Shulker boxes
Smithing tables
Stonecutters
Villagers
Creative inventory screens
In addition, the following are also affected:
Book-and-quills and written books
Recipe Book
The advancements window renders translucent pixels correctly.
I am unable to test if the demo screen background is also affected, however the attached resource pack also retextures this.
How to reproduce
Download and apply the attached resource pack:
Enter any of the aforementioned inventory screens
Expected results
The inventory screen would be translucent.
Actual results
It is not.
Further notes
Comparison using another attached resource pack in 1.14.4 and 1.15 respectively:
1.14.4 | 1.15 |

that's what it should be like
I've updated the description to make it clearer with a table showing the differences, and removed some useless information. Hope you will be fine with this.

Can confirm in 21w11a.

As the reporter of many other UI translucency problems, can I become the owner of this specific report?
