Translucency sorting does not work correctly for intersecting translucent planes
Causes MC-131203 and MC-167319.
Relates to MC-38022 and MC-163098.
The bug
A translucent model which has planes intersecting each other will behave abnormally depending on the viewing angle with respect to what order planes are rendered in.
How to reproduce
A resource pack that remodels purple_stained_glass is attached to this ticket.
- Download and apply the attached resource pack
- Place purple stained glass, preferably a single block in midair
- Fly around it
Expected results
The rendering order of the constituent planes would make sense geometrically.
Actual results
Some planes visibly pop in front of others instantaneously as the player moves, and others are outright invisible behind others.
How to fix
A fix for this could be to split up quads into smaller ones which can be sorted more easily, although this would make more sense as a toggleable video setting as increasing the number of quads needing drawn could hurt performance considerably. It is not immediately obvious how this issue could be resolved in any other ways, to my knowledge.

The bug
For translucent blocks whose models extend out of the block boundaries, issues can be seen when next to other translucent blocks. These effects appear exaggerated next to chunk borders.
How to reproduce
A resource pack that makes white stained glass huge is attached to this ticket.
- Download and apply this resource pack
- Place white stained glass in water
Expected results
Translucency sorting that makes sense.
Actual results
Some of the water tends to disappear depending on your point of view.
I have since decided against said "further optimization" as this would introduce complications due to MC-277806. The currently attached optimization is not subject to this.
Can confirm.
Thank you for your report!
After consideration, the issue is being closed as Won't Fix.
Please note that this is not the same as Working as Intended, as this bug report correctly describes behavior in the game that might not be the intended or desirable behavior, but it will not be fixed right now. Sometimes, this is because the issue reported is minor and/or impossible to change without large architectural changes to the code base.
