Glitchy graphics sometimes can take place on WC_Unicorn

[PokemonHacker1337]

Description of the problem

Sometimes in Unicorn Way (or WC_Unicorn), there can be extreme bugginess with textures. Additionally, after the combat update came out, it seems that standing in certain spots can cause white flashes at random. This isn't a graphics driver or anything, it doesn't happen on the live game

Reproduction steps

Just walking around in Unicorn Way can cause these odd graphics glitches. It doesn't appear to happen in other areas though

Expected behaviour

Normally, I'd expect it to, well, not happen.

I cannot get this graphical error to occur on my Linux machine, but I have seen it before. I believe the effect may be a Windows exclusive one.

This is also visible in the combat trailer! While playing the tutorial you "free" the Unicornway and all broken things around unicornway are removed

Hey! I'd like to work on this one. Mind assigning it to me?

Thanks :)

The wall leaves texture (the glitched textures) is loaded twice (by the two flags). This only happens if you haven't started the first quest, because that quest sets WC_Rattlebones_ButterFlyZone to off (the problematic dynamod).

The ghosts (LostSoul / Ghost-Blue-L01, template 35085) seem to be glitched on this server. They randomly turn into a polygon ball, sink into the floor, stretch their vertices way beyond their limits, flicker, or disappear completely. This can even happen while they are standing still, and you can clearly see it when rotating the camera.

The glitch seems to start while the NPC is moving, usually some time after it spawns.

Sometimes the skin also deforms so badly that it looks like light rays or white flashes. This seems to match what was reported in the original issue: "After the combat update came out, it seems that standing in certain spots can cause white flashes at random. This isn't a graphics driver or anything, it doesn't happen on the live game."

I've confirmed that the issue is specific to the ghost template:

• Replacing the ghosts with skeletons makes the problem disappear.
• Replacing all enemies with LostSoul causes the problem to appear in every zone.

I'm currently investigating why this only affects ghosts and not the other enemies, such as skeletons and sprites, since they share most of the same behaviors.

I've never had this bug on my machine

Works for me.

I've tested on a new device, installing from scratch Aurorium, Imlight and the official client (in the previous case it was the Steam version, this time it isn't), and as you can see it keeps happening. In both cases you have to wander around and move the camera for a while; it usually doesn't happen at the start. Both devices are Windows, so I don't know if it happens on Linux.

After extensive testing, I could not identify the root cause of the white flashes in WC_Unicorn for the ghosts Ghost-Blue-L01 / LostSoul (template 35085). I’m leaving this for now ...

If it weren’t for the fact that it doesn’t happen on the official server, and that I get the same result when testing on two different Windows installations, I would assume it was something client-side, but I honestly can’t find any logic behind it.
