Player will randomly become invisible on servers.
Even if they are wearing armor the other players can't see them. Particles generated by the invisible players (fall damage, hearth, potion effects, etc.) are invisible too.
When you are affected by the bug, you can't see your armor points and you don't any of your sounds (fall damage, taking damage, burning, etc.). You are also immune to melee damage dealt by other players, but you still take damage from arrows although you don't get knocked back. Spectators can not teleport to invisible players and boats used by invisible players will act strangely.
The only known way to fix it is by having the player to relog or kill him.
The bug is about chunk loading on a server. If a player gets teleported in an unloaded chunk, he will become invisible most of the time. If you teleport another player in the same chunks as the first one, he won't be invisible because the chunks are loaded by the first player. If you teleport a player at least 1 tick in the spawn chunks and then teleport them somewhere else they won't become invisible. This could be used as a temporary fix for map-makers.

I have also seen this happen while making maps in the snapshots. Teleporting players large distances seems to trigger it for me. Multiple players will be teleported from one map to another and become invisible/intangible to others. The only solutions for me have been using /kill on the player (when they respawn they are fixed) or having them relog.
Yeah I forgot about that. Since Ao added particles quite a bit of invisible players has been killed and when they respawn they are visible.
This issue has resurfaced on my vanilla server after the update to 1.12. Players will randomly become invisible and cannot be teleported to through the spectator menu and will not become visible until they relog or are kicked.
Traveling to the end and teleporting seems to exacerbate the issue.
Was unsure whether I should comment on this issue or try to create a new bug.
Am encountering this bug as well. We are experiencing this issue with multiple players at any given time.
This is a duplicate of MC-92916, and that's already marked as affected there.
This is a common glitch on 1.9 servers and if you want to know if your one of the invisible then some sound effects don't work. For example, falling in lava & jumping from a high place with that leg break sound doesn't work when your invisible. When we mean invisible we don't mean by the effect, but as in the fact no one can see you. The only way we can get people to get out of this state is if they re-log from the server. I have tested this on many different servers and different snapshots so the bug has been here a while and is real.
