Added picture from MC-61802 showing the bug.

• 14w31a You can see it also very good when spectating a wither boss

Confirmed for 14w34b

Confirmed for 1.8-pre1.

Still affects the 1.8 release.

I think the summary should be edited, changing all the capital letters except the first letter to lowercase and replacing "Torch Flames" with "particles" (as this affects all particles).

EDIT: Thanks, @unknown.

Confirmed. It's like you are in an Enderman with the particles around it, and you are in it moving your view left to right, but the Enderman is keeping you still in your view. It's like possession in 50/50.

Confirmed for 1.8.7. The player's hand also appears to have a similar problem if spectating is invoked via a camera packet versus actual spectate mode.

Confirmed for 15w51b.

The following text is an assumption, after writing it I noticed that it is kind of strange anyways...

The problem is very likely that the client still "rotates" the screen while you spectate an entity. So please change the title to "Client allows rotating player while spectating entity" or something similar.
The reason why the player still looks in the same direction but is differently rotated is probably because in the net.minecraft.client.Minecraft class (MCP 1.8 names) the spectated entity is stored as private Entity field_175622_Z whereas the player is stored as public EntityPlayerSP thePlayer. When the player is not spectating any mob, the spectated entity is the player.
Apperently for particles and sound the data of the player is used whereas for normal rendering the data of the spectated entity.

The reason why you are still able to rotate is that the public void updateCameraAndRender(float p_78480_1_) method of the net.minecraft.client.renderer.EntityRenderer class does not test if the player is in spectator mode and spectating a mob and thus should not rotate.

Confirmed for 1.9

for me it moves the particles around themselves when i try to look around, i can make the fire dance

Please link to this assumption

Still in 1.10.2

Still in 17w14a

Still active in 1.12.

The problem is with the handling of the Camera Packet. When handling the packet, the client doesn't set the player's spectating entity, instead it sets the client's render view entity. This then causes the player's game tick to skip a few logic updates tasks, e.g. updating position and rotation. Thus, causing the player to be out of sync (only on the client), producing both visual and audible issues.

Still an issue in 1.12.2.

Reproduced it while spectating a player in a multiplayer server.

Is this still an issue in 18w21a?
