Spawning is creating ghost bricks in games

Spawning creates ghost bricks, but only sometimes, and for random players it happens more.

Except that whatever update was just released exacerbated the problem. A player in my own game reported seeing “yellow triangles” flickering on their screen and was too fast to screenshot.

Cut to me 20 minutes later testing something in a friend’s game, and I catch these screenshots. These random bricks are local ghosts and flicker and move depending on your position, the time, and your camera angle. And they follow your arm cframe like they’re welded on there somehow.

Fun fact: I had this problem in my Hollow Mansion game… 2 years ago. People had local doors and parts welded to their arms. I got rid of the “weld surface” texture on the doors and coincidentally haven’t had problems since, so maybe it’s the weld surface being the poltergeist?

Also I’m not sure if this is related to the ghost brick bug, but some players that were already in my other game when you join it, are stuck in the air near the spawn (not always on the spawn like in the next picture, but like they walked 30 studs and got welded THERE too.)

This is NOT the common spawn-anchor glitch related to lagging players and games (another bug someone has probably reported, and I’m sure sorcus already knows about since the easter hunt). This is completely local, meaning, if anyone else were to walk back over the spawn, I could jump on this “frozen/ghosted” player and appear to the other players as floating:

I’m not entirely sure what the ghosting bug is about. We did break some rendering-related code in the update yesterday (can result in additional ghosting, random triangles on-screen, crashing and other goodness); we’ll do a patch today to fix that.

If after the patch tonight you have a reproducible ghosting problem, please let us know.

It’s most likely the weld surfaces causing strange flickering, floating geometry

I caught another picture of the elusive strange polygons on top of the weld surface in my other game:

I’ll keep a look out for the patch and stuff

Edit: you mentioned crashing - I’ve been crashing in games so often today and so have people in my games.
It likes to crash the whole server if I teleport to someone using cframe, maybe related to the welds on the sides of character torsos…?

I keep getting this in games aswell now, it keeps poping up different material stretched in to me.
