| Description |
The bugStarting with Snapshot 13w10a, various small particles will visibly jump to the northwest before following their normal path. First seen with void particles, has since been observed with the small whitish particles seen in water, the dust particles that rise from mycelium, droplets from the bottom of blocks with either lava or water above them, the larger round bubbles in water, the droplets of rain when they land, and the green particles from using bone meal on a plant. To view the glitch, simply get to where the particular type of particles would appear and note their movement. Facing either northeast or southwest and either straight down or up (for those particles that appear at the bottom of a block) makes this easier.

OK, I can report that this is resolved as of 18w19b. 👍 I would just do the thing to mark "resolved" myself, but I don't see where in the interface I do that. :o |

I believe I have finally solved this bug, in attempting to fix my own extension of this particle's glitchy movement. Here is the explanation as well as I can give it, using MCP names for the methods involved:

Reasons to fix this ancient bug: Making foggy particle systems look professional enough to spend any time looking at. Some time down the road you might want "freezing fog" as a game element, wouldn't that be tits? Also, this bug most likely tells us that you've got two coordinate systems in the client which have glitched origin points relative to one another. One responsible for spawning each particle and a completely different one responsible for evolving the particles after they leave their spawn points. |

Here you go, Grum. When I first noticed this problem/glitch, it was the Void Particles near Bedrock. I was accustomed to mining around and seeing particle motion like in this clip from 1.4.7: http://gfycat.com/RealisticAlarmingFly But then as of the very next update, the particles would appear for one brief frame, and then jump over the course of 2-3 frames @60fps to a new location roughly to their NorthWest before stopping at a new location and then finishing their "journey" for another second or so prior to fading or disappearing. This behavior spans many many versions, but the last version we can still access that shows it fully is 1.7.10: http://gfycat.com/FrenchBouncyDobermanpinscher By then I was reporting and confirming per version, but I open up 1.8.1-pre3 and see the equivilent of this: (1.8.1): http://gfycat.com/WindingJadedGemsbok Void particles have been summarily removed. :O So, I found a new way to confirm that the particle glitch still happens, but now the test is a lot harder and I never encounter the effect in regular gameplay because the void particles were the primary way to see it. Nonetheless, I can confirm even 15w47c continues the bug. Steps to reproduce these days: open creative mode, either drink a potion of night vision extended (older versions) or it's going to be cleaner to use an "effect of night vision" command and turn off the obnoxious effect-particles in newer versions. Find water at least 8 blocks deep or so. Dunk down into the bottom. Look down near your feet and press F5 for behind the head view (when you have potion/effect particles spamming your view this helps limit the attention-drawing noise that they generate, but also gives you the best view of the water particles). Looking down past your head to the ocean floor at a steep angle helps make the particle-glitch a lot easier to notice. As of 1.4.7, no problem the particles appear, potentially float around by a millimeter or so, and then vanish. For every newer version, the particles glitch towards the NW prior to settling into their ordinary behavior. (Starting with 1.8ish, the noisy potion particles I was too lazy to suppress here stop just wafting upwards and begin to waft out much more aggressively, lol!) Here are the save files I made for each of these test scenarios. In both, you should already be in the right place. Underwater, you have night vision active for several more minutes and a bottle of it in you hand to re-quaff at will. Underwater you WILL need to press F5 to set the behind-the-head view, as that is not saved with the world. In Void Particle save, you don't gotta do nothing but sit and observe. xD http://lightsecond.com/pub/MC-12269%20void%20particles.7z |

I'll get one recorded today, on school now, will behome in about 5 hours, I'll grab the deathSuspend particle, because you can see it the best inthat one, and already have a repeating command running in my server with that particle |

Can anyone got some visual for this? A tiny video/gif/something would be wonderful. |

I'll check if it still happens tomorrow, it's kinda late here now |

I've seen this a few snapshots ago still, not sure if it's still in the latest version too |

Never experienced this in 1.8.8 or 15w47c. Fixed? |

Thanks. You have been given reporter access in order to update the versions yourself. |

I can confirm that the issue still affects 1.8.1-pre3, by going into creative mode, going deep into some water and turning on night vision. Fixing this bug may have dropped significantly in popularity now that the void (which was the easiest place to see it) has stopped showing fog and particles. |

Confirmed 14w33a Makes mining near bedrock really strange. ;3 |

Confirmed in 1.7.1. |

The void particles now move faster starting with 13w36a, making it even easier to see. |
| Comment by WolfieMario [ 06/Jul/13 ] |

I'm hoping they fix this; it's pretty jarring when you're building near the void, and it happens to way too many particles. |

Looks like the green particles from using Bone Meal have this problem as well. |
| Comment by Carl Lystad [ 14/Jun/13 ] |
|
Looks like the larger bubbles from when something splashes in the water as well as the little splashes where rain is falling are also affected by this. (How did I not notice the large bubbles before now?) |
| Comment by Carl Lystad [ 05/Jun/13 ] |
|
Okay, it's looking like all the tiny square particles might be affected. I just noticed the drips from the bottom of a block when lava or water is over it showing the same behavior. Updated the title and description to reflect this. |

Updated affected versions. Good catch on the Mycelium particles. Hadn't noticed those. Guess I just don't spend enough time in Mushroom Island Biomes. |

Also seems to effect mycelium particles. Its hard to tell because they are small, there are less of them and they disappear faster than void particles (I think). |
| Comment by Carl Lystad [ 08/May/13 ] |

Just noticed the bug also seems to affect the "bubble" particles visible when under water. |

Still present in 13w16a. Not really surprising though, since it's the first of the 1.6 snapshots. |

I see that they just go to the northwest no matter what direction you face. Not tested a whole lot though. Cam be seen from a distance, too. |

Confirmed. |

After further testing, the particle movement is toward the Northwest, meaning the direction you face will affect the direction the particles move. Edit: That last part is in relation to screen position. My initial report described the movement as jumping to the right on the screen, but further observations showed the real movement. |
