[2023-11-26 20:06:30.901956050] [ERROR] [alacritty] Alacritty encountered an unrecoverable error:

                                                    	There was an error initializing the shaders: Failed compiling shader: 0:1(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES

With some GTP helps I discovered it has something to do with my OpenGL version and that it has everything to do with my graphic hardware, what is bad as I'm on a Notebook full intel stuff.
Anyway this is my glxinfo | grep "OpenGL version" output:

OpenGL version string: 2.1 Mesa 23.3.0-rc5

What GPT says this Alacritty fork expects the version 3.0, but it is not what the log says. Anyway I hope someone can help cuz I got no idea what to do.

try to modify the files here.
the glsl is hard-coded to be #version 330 core. Maybe you could modify it to #version 210 core and compile again.
I remember that if you downgrade it some syntaxes were not supported.
