I'm on this minecraft world with my friends on telegram (ignore their voices, it's italian) and there's this bug. All my specs and info are on the vids.

https://github.com/xCollateral/VulkanMod/assets/93542339/7cbb39d1-277e-4fce-acf5-2d55a65275df

I can confirm issue on the latest version. For me it's happens on a server and resolves with F3+A.

oh and i found out that if i look to a non complete block i can see the blocks under it like x-ray. Same specs and everything

#402
same problem here with latest v4.0 1.20.4 on 1.20.4

the blocks under it like

mine issue a little different and have been fixed by removing ServerCore

yea but i dont have servercore

Finding which mods are causing the issue would be helpful.

im running on java 17 version 1.20.4 and after 20-30 minutes of loading and changing chunks this happens seemingly at random. VulkanMod_1.20.4-0.4.1
Chunks do not render after a certain distance aswell.
using /back on the server causes the extreme visibleness of the bug as I replied previously using images.

Was running on a server using KingdomsX plugin and not much else directly related to chunks or rendering, nothing forge related.
https://github.com/xCollateral/VulkanMod/assets/91396482/f7f97980-9155-47d8-a8c2-80eacecdfedd

exactly the same, if previously i said that without mods it fixed, it was because i didn't run it long enough

and with 0.4.1 it still has the issue

I don't have server core this still happends exactly like the video

https://github.com/xCollateral/VulkanMod/assets/91396482/0d26c511-805b-4d3d-baf9-89886cf7421d
I managed to fix it.
https://github.com/xCollateral/VulkanMod/assets/91396482/e806d59d-0625-4971-b4f9-c9c98f245bba
By disabling all optimizations and turning render/simulation distance to lowest.

Edit: just changing chunk render to 2 fixed the issue. after re-putting to 12.

Send logs and steps to reproduce, please.

the steps are easy i think, launch the mod, go on a random chunk, break blocks, for some reason it worked only on some chunks, and second, about the logs, i think i might have found something:

I tried to reproduce it multiple times but could not manage to. Could you try if that happens without any other mod?

im gonna try

yea hum, i tried and it seems that without every other mod the issue gets fixed

Could you check if the issue still occurs with the latest commit?

sure, ima do it

@xCollateral Can you send a compiled development build of 85e583d ?

using what melamit suggested to install, the bug in action. seperate case. I did not check if the blocks updating bug was still an issue. It seems to be gone. will edit if occurs in rendering.
It is now chests/interactable blocks that dissapear after 20-30 minutes of gameplay.

I recommend not to use TLauncher, many reports that it is unsafe to use, don't have any proof but still, be careful with it. I recommend to use ShatteredPrism, you can check it's source code and unlike prismlauncher it supports FTB and Offline auth

i dont have so much freetime lately, can someone that has this issue check for me?

i think it might depend on the device maybe or the mod itself, I just used the Vulkan mod solo and traveled out until after the spawn chunks and the blocks weren't disappearing after being broken or appearing after being placed.
And in the video the other guy showed, it was pretty laggy. And my device is also really bad.

I will check. But it's hard, because I don't know how to reproduce the issue, other than just playing.
So, I just download artifact from here? https://github.com/xCollateral/VulkanMod/actions/runs/9419390665

dad55e7 should have solved this issue. Can someone check if it's still happening or not?

Latest version (0.4.3) should have solved this issue.
