Iris 1.8+ crashing on launch (intel linux)

Every time I attempt to load Iris, the game crashes on launch with the below error. It works fine when I load Sodium without Iris. I am running on linux (per glxinfo:

OpenGL renderer string: Mesa Intel(R) UHD Graphics 620 (KBL GT2), OpenGL core profile version string: 4.6 (Core Profile) Mesa 24.3.1

), and have tested with multiple game versions + compatible combinations of iris/sodium patch versions. The error:

You might be running into a system-level bug Try opening the config file at config/sodium-options.json in a text editor And change the value for option use_no_error_gl_context to false After saving the file, try restarting Minecraft.

Rats, that's what I was afraid of Disabling error checks got it running (thanks for the tip!!). Still curious what the root cause is... Based on elsewhere it may be an interaction between Mesa/LWJGL/the bundled GLFW build, that's Linux for ya
