How to find crash reports and logs

If your issue involves a game crash, please locate the crash-reports folder in your .minecraft directory and drag the relevant crash report into Discord.
If your issue does NOT involve a crash, or there is otherwise no available crash report, please locate the logs folder in your .minecraft directory and drag the file named latest.log into Discord.

Please click yes when the Allium bot asks if you want to upload the file to mclo.gs

Seems like ChatGPT has similar response as what I'm about to give.

With that said, Iris has not been tested on Qualcomm powered Windows system, so the statement by ChatGPT is likely true.

singyRay•7/6/25, 2:05 AM

oh ok, so this issue can't be fixed?

hardester•7/6/25, 2:11 AM

If it was the cause, then it's unlikely to be fixed anytime soon since nobody in the dev team has a Snapdragon laptop to even test it.

One thing you could try and get things working is running Minecraft with just Sodium and Iris installed, try and get shaders to load with just those two mods, see if it works.

singyRay•7/7/25, 7:31 AM

i tried, it didnt work. its ok ill play without shaders until it gets fixed.

singyRay•7/12/25, 9:45 AM

is there anything i can downlaod that would help solve this issue

SsingyRay i tried, it didnt work. its ok ill play without shaders until it gets fixed.

You need GPUs that are compatible with Iris Shaders

hardester•7/12/25, 9:55 AM

Some good news, your GPU supports Vulkan, which means you could get Minecraft running through Zink, an OpenGL compatibility layer on top of Vulkan. Unfortunately this method is viable on Linux-based operating system, not Windows.

Inverted Nexus•7/12/25, 10:19 AM

yep, but it's sad that we can only run zink through linux

singyRay•7/12/25, 1:39 PM

oh, ok. I was just wondering, becuase iris worked perfectly with minecraft 1.21.6, but the update messed it up for me. Thank you for the support though.

hardester•7/12/25, 2:01 PM

1.21.6 works but 1.21.7 doesn't?

hardester•7/12/25, 2:01 PM

hardester•7/12/25, 2:02 PM

That's most likely regression. @IMS care to inspect?

hardester•7/12/25, 2:03 PM

May need to reproduce this issue and generate a new log, send that over without having it going through ChatGPT.

hardester•7/12/25, 2:03 PM

Generate log for both 1.21.6 and 1.21.7.

Do you want to upload this file to mclo.gs?

mclo.gs is a website that allows users to share minecraft logs through public posts.
It's easier for the mobile users to view the file on mclo.gs, do you want it to be uploaded?
