Using Fedora 41, Prism Launcher from flatpak, AMD RX 5600XT

when holding hand out:

when holding diamond gear:

just found out it happens on golden apples and amethyst buds too, there might be more.

Same Issue here. I was trying to figure out what was wrong till I found this. I'm on Bazzite (Fedora 41) 7900xtx on prism launcher

I can also reproduce this on Arch with an RX 6600, running Mesa 24.3.4. If I hold glowstone in my hand, while using a vanilla instance with the Solas shader, the entire world turns black until I stop holding the item.

Interestingly, this does not seem to affect another system using an AMD card of similar vintage on Windows, suggesting it might be some interaction between the shader and Linux.

Disabling dynamic handheld lighting in the shader settings appears to be a workaround that makes the game playable, at least.

I have the same issue on Linux Mint with my RX 5700. Anything that counts as a light source in-hand renders all blocks 100% black.

I also have the same issue as well on steam deck oled. If you guys could come up with a fix, that would be great. I know it has something todo with either Volumetric Ligh option or the Dynamic Handheld Lighting option.

Thanks

I'm able to reproduce this issue with any light emitting handheld item, it seems to be directly connected to the Dynamic Handheld Lighting option and Linux AMD systems as previously mentioned here. I've experienced similar problems to this in previous versions as mentioned in issue #49.

I'm hesitant to rule out Iris however as I've experienced glitches like these with other shaders. Could also have something to do with the AMD driver and how something on the graphic stack (be it the shader, Iris or whatever) expects it to behave. Anyone try this with the proprietary AMDGPU-PRO drivers?

OS: Gentoo
GPU: RX 7700 XT
MC: 1.21.4
Java: 21.0.6
Iris: 1.8.5
Launcher: Prism 9.1
Relevant Mods Used: Sodium, Lithium

I can reproduce this with Opensuse Tumbleweed
GPU: AMD Radeon RX 6650 XT
MC: 1.21.4
Prism Launcher Flatpak
with iris

I'd be happy to contribute any debug logs and stuff if told how

reproducing this on Arch Linux with dynamic lighting on while holding anything iron

GPU: AMD Radeon RX 7800 XT
MC: 1.21.1
Lunar Client launcher
running iris+sodium

If anyone that was able (or unable) to reproduce this can test the patch to make sure it works as intended that would be great. It worked just fine for me as far as I was able to test it, but I didn't have much time to try every light emitting block, and who knows, might just not work for someone else.

Thank you all! :)

All items that didn't work before work now, thanks a lot!

everything works properly now on the latest version
