Bug with mod Legendary Survival Overhaul (https://www.curseforge.com/minecraft/mc-mods/legendary-survival-overhaul) .When you die while playing online (when the player is still lying on the floor), all buttons, menus and elements disappear from the screen, and the game starts to lag a lot. Even if you press Esc, there will be no buttons on the screen, they will be invisible.

How it should be:

Bug (all menu elements are invisible and the game is terribly slow):

I have looked into this issue and I do not see anything I can do from my end. I think you should report this issue to the mod and link it here. I will try to join the conversation and see if a fix can be worked out.

Can you send me the log file? Pretty sure the low fps comes from errors in the log.

Here is the latest log. I used only your mod and Legendary Survival Overhaul.

You were right, almost the entire log is filled with errors.

Hello there, I'm the dev of LSO
I don't see anything about LSO in the log file, could you guide me on what's going on there ?
Thanks !

Hey @sfiomn,
actually I have no idea what is going on. I don't do anything special. I load in an entity post effect and render some text. Code can be found here:
https://github.com/CreativeMD/PlayerRevive/blob/1.21/src/main/java/team/creative/playerrevive/client/ReviveEventClient.java#L126-L211

Apparently the post effect is not being processed and the text does not appear.

Hello, found the issue, it was on my side
My "low hydration" effect would kill any blur effect if the hydration isn't low enough, I've clean this part of the code and now all is good

Thanks a lot @sfiomn.
Glad it could be solved. Have a nice day!
