Ghost chunks appearing when flying through a pre-loaded world forcing chunks to load.

Flying around in a pre-generate world with /vdist showing I have a full active 16 chunk render distance, I seem to occasionally come across chunk rendering corruptions.

Flying near / through it and rotating my camera around, the corruption flickers. Sometimes the ghost chunk is in large areas, other times it's just a single 1x1 chunk in the middle of nowhere. Teleporting away and back again, the chunks re-send and display perfectly fine.

Many players in my community are also reporting a noticeable occurrence of these ghost chunks since BVD was implemented.

@graywolf336 Do you perhaps have any ideas in how to lessen the impact of these ghost chunks?

Nope, and it happens on my server. I think it is the poor Minecraft client getting extremely confused 😂 I don't have all the time to investigate into why, but if I manage to get some then I'll look into it

@graywolf336 Is there any possible way to validate chunks before sending? Or perhaps send slower to prevent issues with the client getting confused? I still seem to run into this issue quite often with dev 18 (your fork) and lots of players asking about it. :(

[graywolf336]

Without getting into packets and intercepting them (which I honestly have no desire to do), I don't know. Can it be reproduced without the plugin and a high static view distance? If so, then that would be an issue with Minecraft or Spigot or Paper that is out of the plugin's control. 🤔

I'll have to give it a test in a clean environment later tonight. My production environment is quite heavy.

Please try without BVD, then with the latest dev version of BVD. Let us know what happens
