Entity NBT isn't always synchronized with clients immediately, rendering the entity incorrect for a brief moment
An alternative description is provided in MC-72774.
Code analysis by Marcono1234 here in this comment, he narrowed down the apparent issue of this bug.
Using the new EntityTag feature for custom spawn eggs, I created spawn eggs summoning a Squid with the invisibility potion effect, but while I was demonstrating the "Tags" tag by placing the spawn eggs against a barrierblock, one Squid popped into my face ;_;
Give-command for a custom squid spawn egg:
/give @s minecraft:squid_spawn_egg{EntityTag:{Glowing:1b,NoAI:1b,CustomName:'{"text":"Invisible","color":"dark_blue","bold":true,"italic":true,"underlined":true}',active_effects:[{id:invisibility,amplifier:1b,duration:1200,show_particles:1b}]}}
It seems that the effect is not always (or generally?) applied immediately.
In current snapshot 20w12a it is visible each single time I use the spawn egg; that has not been always the case, e.g. back in 2015.
The Squid appears for about 1 tick.
This seems to generally apply to every changes that you'd summon an entity with, e.g. also Rotation value:
/summon mooshroom ~ ~1.5 ~ {CustomName:"RandomUUIDCow",CustomNameVisible:1,Rotation:[270f,0f],NoAI:1,Silent:1}
The summoned Mooshroom needed 2 ticks to get into the 270°-positioning.
The default position an entity "looks" - including the player in a newly generated world - is always South, and also that Mooshroom in this example looks at South first before it gets turned into the desired position.
As that's the confirmed case now, the title should be changed, but I'll leave this to the experienced mods to find a title which can describe the totality of the problem }=)

Forward resolved to MC-88181 - there is described the cause of this behaviour
We could seperate MC-88181 and this report a little more by saying that MC-88181 is not caused by a missing onUpdate() call for the entity.
For example the problem that you see PrimedTnt for 1 frame is that the S0EPacketSpawnObject (MCP 1.8 names) contains only basic information about position, rotation, the entityId (acts as entity index), the entity type id and one additional integer. After that other packets are send containing the other needed information. However while the second packet has not arrived the entity has not all information. For example PrimedTnt. This applies for example also for armor of mobs.
Additionally for PrimedTnt the S1CPacketEntityMetadata packet which is send after the spawn packet does not contain the correct fuse value. This seems to be caused by the DataWatcher not watching the fuse value.
Relates to
Please link to this comment in the description of the report.
The following is based on decompiled version of Minecraft 1.8 using MCP. All method and class names are the names used in the decompiled version.
There are two reasons why this happens. The first one is that the client does not know that the item or in general any entity is Invulnerable (this is because none of the packets send to the client contain this information, see also MC-72774 and MC-88181). The second bug is that the public boolean attackEntityFrom(DamageSource source, float amount) of the net.minecraft.entity.item.EntityItem class acts server- and client-side, which is why the fact that the client does not know that an entity is Invulnerable matters. Other classes like the net.minecraft.entity.EntityLivingBase class only run this method server-side.
same issue as MC-88181
Same issue as MC-88181.
This was fixed in 16w44a and is still fixed in 1.11. It is difficult to pinpoint the exact fix version, because 16w43a behaves super weird and MC-88181 can not reliably be reproduced.

This is MC-88181, just a survival method.
This bug is not a duplicate of MC-88181
This bug does not affect versions prior to 1.15 unlike MC-88181 (tested in 1.14.4 and 1.12.2)
This bug is related to protocol change in version 19w34a (1.15)
This version removed the Metadata field from the Spawn Packet.
For example, if you summon an entity with an invisibility tag that is applied beforehand (for example, using the Bukkit API), then with some probability you will see this entity for 1 frame, the probability will increase if the client has a high ping or high fps.
I don't see any reason why this was done, since the server sends the Metadata Packet after the Spawn Packet anyway.
Possible solutions to the problem:
- Return metadata field to Spawn Packet
- Make it so that the client does not render the entity until it receives the first packet of metadata about it
- Add boolean invisible field to Spawn Packet (I think it's a bad idea)
Most likely these solutions will at least partially fix bug MC-88181
UPD.
If you decide to fix this, it would also be cool to have an Equipment field in the spawn packet, it will also make life easier for plugin developers
Sounds like MC-72774
Thank you Nasm, it seems to be related, indeed!
Not sure if "EntityTag" and custom spawn eggs also should be consideres as own issue, as it's a new tag for entities/spawn eggs, but in the end it might be just the summon after all, or rather that they don't always have their specific attributes assigned to them in the very first tick of their existence.
I'll update my bugpost }=)
Made this the new base ticket, because here is the cause of the behaviour described.
I have updated MC-72774 with new information and will continue to do so as I explore this bug further. Please make it the primary report.
This is not a "fight about who owns a bug report", it is about fixing bugs.
As I'm frequently dealing with mobs for contraptions/inventions, I also plan to add more information if I find out anything new.
I'm not a fan of quarrels on that level, I'll leave it to the mods.
I only want this to be fixed, if possible.
Regards, Meri
This is incorrect as the EntityTag data and NBT from /summon is applied to an instantiated entity class first before the entity itself is spawned in the world. For instance, with /summon, the createEntityFromNBT() function is called first using NBT from input, and is then followed by spawnEntityInWorld(). The mobs should theoretically be invisible before spawned, and while that's the case almost every time for me, I'll get a rare "flash" of a visible mob before it disappears.
It's more likely to do with potion and rendering updates than NBT. Quick check in MCP shows that stored effects are one of the last things updated when an entity is ticked (and by the looks of it, while the effects are read from NBT right away, they essentially do nothing until the entity is ticked for the first time). Needs a much more keen eye than mine to get down to the bottom of what really causes it, though.
It seems that this is caused by the packets send. First a S0FPacketSpawnMob (MCP 1.8 names) is send, however apparently this packet does not contain the effect information (this is probably the bug) and after that a S1CPacketEntityMetadata packet which contains the information about whether or not the entity is invisible.
To fix this before the entity gets summoned the potion particle, ambient and invisibility flags need to be updated. This can be done by calling the method func_175135_B() of the net.minecraft.entity.EntityLivingBase class (the fire flag seems to be set correctly). This could be done from the func_151260_c() method of the net.minecraft.entity.EntityTrackerEntry class.
Note: It seems like in 1.8 in case a DataWatcher is send in a packet, the complete DataWatcher is send. What this means is it contains also the entity itself (as owner). That kind of negates every savings in respect of packet size.Eventually the handleSpawnMob(S0FPacketSpawnMob packetIn) of the net.minecraft.client.network.NetHandlerPlayClient class should also run var10.getDataWatcher().updateWatchedObjectsFromList(var14); before the entity gets added to the world.
Thank you very much [Mod] Skylinerw and Marcono1234 for looking into it and clearing this up, I was worried it wouldn't be really fixable, but now it seems it is }=)
I'll update my bugpost later (after work) and add a link to the comment with the code sniplets, so the Devs can see it, as soon one of them will take care of this bug.
Happy, also on behalf of all the mapmakers I heard complaining about it, so thank you again for your help };]
This might affect the spectral effect as well depending on whether or not this is stored as a flag (which should be the case).
4 months ago, when they added EntityTag to spawn eggs, I created a glowing sheep, but didn't notice that its effect was applied later for at least some of them, but it would indeed make sense if it would.
I'll record the summon via custom spawn egg process soon and then go through the footage frame by frame, maybe there is evidence for it }=)
Thanks for reminding me of this effect, I totally forgot it.
Will post any conclusions for it then as soon as I got the visual results.
Edit: Just realized I already mentioned also "Glowing" etc. in my bugpost ;-;
I forgot I already did, but what I definitely didn't do was recording it to see if the effect gets applied a tick later for some of them, it's harder to spot than if an e.g. invisibility effect fails.
My duplicate
MC-101073descibes an example that should be easier and more reliable to reproduce. Hopefully it helps you out!This was fixed in 16w44a and is still fixed in 1.11. It is difficult to pinpoint the exact fix version, because 16w43a behaves super weird and MC-88181 can not reliably be reproduced (but
MC-101073can).It's not fixed, it still affects the newest versions.
This issue is not always noticeable.
20hz summoning of invisible armor stands, only 1 per 10 seconds doesn't instantly become invisible. (at least, for me.)
Adrodoc55 It definitely is not fixed, at least 1.11.0 inclusive.
I, as the responsible one for this bugpost, would not update it to a new version if I couldn't reproduce it.
I mentioned at some point that it has gotten way better (during the 1.9-versions iirc), but it still is reproducable, albeit it can take a bit until it shows, like user-f2760 mentioned.
With the spawn egg incl. an ActiveEffect it was never "reliably reproduceable" in the meaning of: It never showed always (at least since the reported 15w36d), so I don't quite get what your point is?
It is still "reliably reproduceable" in the meaning of: It does show at some point.
An e.g. inserted Rotation value is still very much/immediately noticeable in most of the cases, that the entity firstly "looks" towards South, before it turns into the Rotation the spawn egg EntityTag included, maybe you want to try out that instead, if you need faster reproduceable results.
I personally focus on the ActiveEffects, but of course I occasionally also test things like that Rotation-value-problem I also mentioned in the bugpost.
In that case
MC-101073is not a duplicate and should be marked as fixed. I must admit that I didn't put that much effort into reproducing this bug, because my "duplicate" is what I was mostly interested in.Confirmed for 1.13pre4.
Confirmed for 1.13-pre6.
Confirmed for 1.13-pre7.
Confirmed for 1.13-pre8.
This might be fixed in 1.13.At least it seems to be a lot harder to reproduce in single player.I was able to see an invisible squid, but only by pausing the game in the right moment.But by just spawning them I wasn't able to find a single visible one in hundreds of attempts.It should be tested in multi-player as well before it actually can be considered fixed though.@edit 1: Confirmed for 1.13.
I'm not sure why I had trouble to confirm it at first. Trying again it was really common.
@edit 2: It seems to have to do with how busy the system is. If I play a video on the same screen it seems to be much more likely to happen.

Isn't this bug "work as intended"?
No, it's not. Why would rendering the entity incorrectly on the first frame be by design?
Priority has already been assigned a while ago, which means Mojang saw this already too. It's still open.
This bug has not been fixed for years and is still unassigned. This suggests that Mojang is either unwilling to fix this bug or is unable to fix it for technical reasons. Shouldn't the resolution for this bug be "work as intended" or "will not fix"?
Not being on the current work track != not going to get fixed. This might require a bit of a rewrite to fix that's just not a priority right now.
Age of an issue never means anything regarding it's resolution.
