Shaders broken on purpur servers
Shaders work fine in singleplayer worlds, fabric servers, vanilla, etc. but for some reason on purpur servers they break.
On purpur servers, the end and nether use the overworld settings, making everything look... awful.
Some other people on the server I'm playing on are also having the same issue.
I tried with my modpack I'm using and with only sodium and iris, still the same issue...

I cant see name tags through objects
when i turn off the shaders the name tags just looks normal, i tested 5 shaders and it seems that the problem is the iris, im not using any mods, can anyone help me?

game not launching when using a certain combination of mods
I've been trying to use distant horizons 2.2.1-a, chunky 1.4.16, and a worldgen mod (big globe 4.5.0) together. unfortunately, the game seems to not want to work at all when trying to use some combinations of the 3. here's what ive tested:
chunky or big globe on their own: works fine
chunky and big globe: works fine
dh with chunky and/or big globe: see first image
dh and iris 1.8.0-beta.4+1.21.1 on their own or with the other 2 mods: see second image...

game crashes when i disable and enable shaders
Iris 1.7.5 became unstable for me, performance went down. But the main issue that when i disable and enable shaders game is completely crashes. i've already tried downgrading the iris but the problem remains the same, any ideas how to fix this?
i also think there is could be possible mod incompatibilities...
the game crashes whenever i play with iris, if i remove it, the game works just fine
this is the following:
begin.csh not working on Iris 1.8.0-beta.6+1.21.2-fabric
begin.csh is not working for me on both 1.21.2 and 1.21.3. It works fine on 1.21.1 with iris-fabric-1.8.0-beta.4+mc1.21.1.

Sadly, Ive no clue where I can contact them, so I thought that I might as well ask here first if somebody knows a fix
The copy and paste error it gives me is the following:...
Missing shaders tab
Im trying to get shaders on forge 1.20.1. When i use sodium + iris there is the changed gui, but there isnt any ,,shader tab,, where i can turn on the shaders. I tried using rubidium and oculus + iris but it gives me this error or error 1 and keeps crashing. Same happens with optifine (error code 1). Got any idea how i can use shaders on forge in 1.20.1?

Create Contraption models disjoint at random, SPECIFICALLY in multiplayer
To preface: I've been working on a personal modpack (Minecraft ver. 1.19.2, Fabric loader ver. 0.15.7) for a friend group of mine, and I also host a server which runs that modpack. Notably, it includes Create Fabric (ver. 0.5.1-f-build.1416) and Iris (ver. 1.6.11). I've been gradually debugging the modpack for a long time now, but there's one bug in particular that's been particularly difficult to pin down: The main mass of a Contraption's model (all of the non-animated cubes) will sometimes spl...

wheres the download for the iris and dh for curseforge?
i saw a video by flowstate on how to get the dh and shaders from iris to work together, and the channel was the dh testing and now its gone, and when i looked in the ones that i could use, it was for modrinth, not curseforge.
