OpenGL - Rendering issue on Minecraft caused by latest 25.10.2 drivers for RDNA 3+

[Alexandre-slw]

Hello, I am a Software Engineer at Lunar Client, a popular third party platform for Minecraft, users started reporting rendering issues after the latest AMD 25.10.2 update that happened October 29th 2025, as you can see on the following screenshot, it looks like any block that is not transparent do not render.

Users reported that downgrading to 25.10.1 fixes the issue.

We also observed that changing the game directory path from the default C:\Users\<user>\AppData\Roaming\.minecraft to a random path while keeping the same content fixes the issue, which makes us believe that it is an Application Profile / Optimization that applies to Minecraft specifically that is causing the issue.

The issue happens when running the Sodium rendering mod on Fabric Loader, but not all launchers are impacted, for instance the official Mojang's Minecraft Launcher does not have that issue.

We know that the issue is happening on our platform, Lunar Client, but also on Feather Client, and on X Minecraft Launcher, the latter does not have any additional modding to the game than any other launcher as far as I know, so we are not sure why these platforms are affected. I do not know if these are the only platforms impacted.

Reproduction steps:

• Run Minecraft version 1.21+ on any of the mentioned platforms, with Fabric Loader and the Sodium mod. If using Lunar Client, Sodium is bundled by default in the Fabric Module.
• Enter a world.

Best case scenario would be to get the issue fixed in the driver, but we would also be interested in knowing why these platforms specifically are impacted and not others like the Mojang's Minecraft Launcher, so we can maybe match their behavior and fix it on our side.

The sodium development team did some research into why this is happening and you can see some of their findings here: CaffeineMC/sodium#3318

@Alexandre-slw We've implemented a fix for this issue in our internal driver.

Modrinth App

Are these all the rendering issue you've encountered?

@baozholu-AMD That is awesome thank you very much, I have seen reports of the hand disappearing, but I think most people encountered the blocks not rendering on our platform

Is that something you have been able to reproduce?

@Alexandre-slw Are these all the rendering issue Lunar Client encountered?

I'd like to invite you to register at https://vanguard.amd.com/ and test our Vanguard driver :
(1) Test the fix once the fix is included in the vanguard driver.
(2) Report any additional issues if encountered
This would significantly expedite the fix and find more potential issue, as it could take considerable time for this fix to be included in the public Adrenalin driver.

Note: Vanguard is not a public community and Vanguard as a group apply their own selection criteria, therefore let me know when you've signed up and tell me your nickname so that they can look for you in the applicants list.

Sounds good thank you, I am still waiting to get my application approved, I’ll let you know

When registering the Vanguard, provide sufficient information and explaining why you want to get the Vanguard driver.
Better to attach this #74

I did attach this issue explaining that I was invited to test that fix, I still do not have access to Vanguard unfortunately
Also, in case that changes anything for the fix, the issue now also impacts RDNA 1 and 2 driver on Adrenalin 25.12.1
