Crash on 1.21.7

Hi All, So I was playing on 1.21.7, and right after I broke one of the new bushes, I got a crash and this was on my client-console:...

Incorrect version on curseforge?

On curseforge, it says fabric for 1.21.7, and the tag says 1.21.7, but on the versions page it only shows 1.21.6 making it difficult to install on a curseforge modpack. I think this might just be an issue with the naming, as it is just on the fabric one?

Bug my friend encountered, or likely incompatibility.

It appears to me that the screen is generating down and to the left of where its supposed to? He's had this issue for a while, and is running the same mod pack as the rest of us. It's possibly just his computer, which would suck, but he's been able to use shaders in the past. We have distant horizons.

rendering issues 1.21.6

Hi, been using iris for a couple months now without any problems. However, once updating to 1.21.6 I noticed my game was extremely buggy and rendering issues took place. I've removed all my other mods (I use Fabric) and the bug still persists.

iris causing rendering issues?

im playing on a 1.20 aternos server with a few other mods but everytime i use iris the ground never seems to render in. it also persists if i turn off the shaders so long as iris is on the modpack. any idea what could be causing this?

Wrong Version in CurseForge

Hi, don't know if it's the right place for it, but the version name is

Iris 1.9.1 For Fabric 1.21.7

Iris 1.9.1 For Fabric 1.21.7

and the game version in CurseForge is 1.21.6, and therefore I can't install it on my modpack. Thanks!...

iris and/or sodium preventing launch

im playing my own custom made modpack on 1.20.1 and after going through every mod individually it seems to be iris and sodium causing my issue. when i disable those two, everything launches just fine. now when they're enabled, i dont get any sort of crash error, which is what confuses me. it either just simply doesnt launch the game, or it does launch but says (not responding) for only about 2 seconds before closing itself and providing me no crash report or anything like that. it doesnt even se...

[my own mod] fluid fade doesnt work when shaders are enabled

what its supposed to look like (no shaders) vs what is looks like with shaders is shown in the attached pics i tested with complimentary and bsl, both of them caused this issue does anyone know why this would happen? https://github.com/AnAwesomGuy/fluidvoidfading/blob/master/src/main/java/de/dafuqs/fluidvoidfading/mixin/SodiumDefaultFluidRendererMixin.java...

can you convert a labpbr pack so it works with integrated pbr+ on complementary reimagined?

the integrated pbr+ option allows for the shaders emissives like ores and amethyst to work, but my AVPBR retextured pack only works with the labpbr option which disables the ores and amethyst emissives. is there any way i can convert it relatively easily so it works?

Patrix texture pack connected textures on 1.21.6

So patrix requires a mod called continuity and it doesn't have a 1.21.6 version are there any alternatives?

as soon as i press f5 my game crashes

there was no crash report so i asked chatgpt and he told me to send latest logs. i sent them and he said there was a crash. he said to disable iris or to downgrade to 1.8.x but i cant because im on 1.21.6 so either disable it or wait for a patch. this is the exact error: java.lang.AssertionError: Can't. at iris$getRenderTarget (class_1921.java:1351)...
