Whenever someone is killed while they're invisibile, they remain invisible forever.
And during these times, some don't have invisibility swirl/effects appearing.
Deaths caused by potions have a tendency to create this bug as well.
Only two known solutions, in game, to this problem is to either kick the person or heal them.
Steps to Reproduce:
1. Drink a invisibility potion. Either 3 minute or 8 minute. (Not a splash potion, it does not cause this bug)
2. Have a sword or bow or even potions kill you.
3. On respawn, walk around and you instantly disappear.

On one server I play on, if you "manage" to kill the invisible-glitched player, they still remain invisible.
Is this still an issue in 1.4.5?
Seems so: MC-3863
I hate this bug, since i play on a 1.4.5 server that i was moderator. A day when i was going to pvp someone for fun, i was invisible and when the guy killed me, i respawned, walked some blocks and still invisible. D:
yes still in 1.4.5. is it confirmed this is really annoying me and i want it fixed.
so confirmed yet? happens too often
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Yes, you're right.
When you die with invisibility on multiplayer (like when you hit the ground to hard or someone kills you), the effect stay forever but could be remove if you die again.
