Shaders don't work on Linux (Ubuntu based distros)

[jaimetavares-code]

Today I installed Pop!_OS, because I really enjoyed the Stracciattella shaders, while I was playing on Windows, but wanted more FPS, so I decided to install Linux.

Testing multiple Ubuntu based distros, the shader either crashes minecraft or simply doesn't work. This might be an issue with my configuration, but every other iris compatible shader works perfectly.

I hope is not too much of an inconvenience to ask you to fix this, and make it so the shaders work on Linux.

Extra information:
OS: Pop!_OS 22.04 LTS
Kernel: 6.2.6-76060206-generic
CPU: AMD Ryzen 7 5700U with Radeon Graphics (Integrated GPU)
I have installed the latest AMD drivers, but nothing seems to work.
Fabulously Optimized (latest)
Minecraft 1.19.4

Edit: this only happens on the latest version of Minecraft. I tried it on 1.19.3 and the shader works perfectly.

Also broken for me on gentoo.

Funnily enough I'm actually developing on Lubuntu, so tbh i don't know what's going on.
I don't have too much time on my hand at this time, so it'll be some time until I investigate it more closely.

net.coderbot.iris.gl.shader.ShaderCompileException: lines.vsh: 0:1(10): error: the compatibility profile is not supported

This seems to be the issue. It looks like your gpu doesn't support the OpenGL version/profile I use.
Considering it doesn't happen on all minecraft versions, it's probably Iris' fault though. I don't think I can really do anything in this case.

Considering 1.20.1 is out now, does the issue persist?
Also, have you tried OptiFine? If it works on OptiFine, that could point to Iris being the issue
