Have not yet been able to repro this case myself. You can no longer duplicate ominous banners through crafting, so that's one less case where this would happen.
Confirmed for 1.14 Pre-Release 5. I just got a banner from a patrol captain which doesn't stack with the others, also from patrol captains.
Can I call confirmed for 1.14.2 pre-3?
I still keep getting Ominous Banners that don't stack with each other. Oddly, every time I update to a new snapshot, it seems like the existing ones that don't stack now stack and some new unstackable one happens.
Still experiencing this issue in 1.15.2 (banners were generated in 1.14.4).
Videos are attached.
It appears that one set of banners has the NBT value `tab.BlockEntity.id` while the other banner lacks this value.
Note: It appears that the banners can be fixed by placing the banner on the ground, and mining it. This makes it so the banner does not have `tab.BlockEntity.id` attribute. (Works in 1.15.2, but does not seem to work in 1.14.4).
I'm currently facing this issue, too. Pillager banners from creative don't stack with ones dropped by Pillagers either, even after you place both banners on the ground and mine them back up.
Still present in 1.18.1; I think I was mistaken or confused in my testing methodology when I thought it had been fixed before. Should either this or MC-151793 be closed as duplicate, since it seems like it's the same core issue?
To summarize: any banner with a pattern (not just ominous banners) that has not yet been placed seem to erroneously have an additional NBT tag that is lost when it's placed in the world, which prevents them from stacking. I think this is most easily seen by reproducing the bug and running /data get entity @p
To reproduce: craft two blank banners of any color. Use a loom and some dye to add a pattern to one, then use a crafting interface and the blank banner to copy it. They will stack. Place and break one of them, and they will no longer stack. If the banner does not have a pattern, they will still stack, and if the banner is placed and broken before copying it, they will still stack.
