[MC-35920] Some translucent parts of entities make translucent blocks, block entities and some entities invisible (depending on loading order)

The bug

These entities/blocks are not rendered behind translucent parts of some entities (later they will be referred as affected entities)

Translucent blocks (stained glass, slime blocks, ice)
Block entities (chests, signs, mob heads...)
All entities that are loaded after the affected entity (usually those that were spawned or have entered the chunk after the affected entity, or are in farther chunks)

Affected entities

Note: in following screenshots all entities are inside one chunk, the order of summoning them (or entering the chunk in case of a player) is

armor_stand with diamond_helmet
affected entity
armor_stand with golden_helmet

Only armor_stand with golden_helmet behind affected entity shows the issue.

Entity (or part of it)	Screenshots	Notes
Translucent `item` (`stained glass (pane)`, `slime` block, `ice` block)	[media][media][media]
`Stained glass pane` (translucent thin item ❓ ) held/worn by entity (player)	[media][media]	Can be seen with players in third person mode
Outer `slime` layer	[media]
`Enderman` neck	[media]
Charged `creeper` "armor"	[media]	Armor of invisible creeper is affected by MC-103462

Confirmed.

don't think I'm understanding the issue. Glass has always done this (as far as I can tell)... people complained cause the new glass didnt work like regular glass and now that it does there's a bug? seems kinda counter productive.

though this probably has more to do with the fact that blocks behind blocks don't render until the block infront of them is broken as this was a memory issue fix mojang did a while back (1.2 or 1.3)

Th3F4114n0n3: I think this is an oversight with the fix for MC-1379 - this wasn't an issue before, because item drops didn't use alpha blending until 13w42b.

Still an issue in 1.7.5 and 14w08a with fast graphics

Confirmed for 14w11b

This bug also affects Chests, signs, and Mob Heads. All of which are block rendered as entities.

(my issue for that was marked as a duplicate of this)

Confirmed for 14w25b.

This is probably never going to be fixed. Order-independent transparency is the proverbial white whale of real-time rendering, and short of forcing everyone to use OpenGL 4, it's literally not possible to fix.

@Ryan Holtz, So it appears that the appropriate resolution is going to be a "Won't Fix"?

Is it the compositing or the ordering that's the problem? Even compositing in whatever order the geometry arrives in would be less disorienting than the current way, which makes it look like the closest translucent object is cutting a hole through the others.
