Issues with binding image texture to compute shader

[speediplayz]

I have been trying to get compute shaders working with Silk.NET OpenGL, and i have got it to a point where they compile and link fine with no errors, however the issues start with trying to bind an image to the compute shader for reading and writing. if i use a 1x1 texture it works just fine, and then i can read the data back and print a pixel (the test shader simply sets pixel 0, 0 to red), but when i change the texture size to 2x2 or anything else, it suddenly stops working, pixel 0,0 suddenly reads 0,0,0,0 and I cannot figure out why.

Compute is just an object to store the program id etc

            Compute comp = new Compute("testCompute.comp");
            uint testTex = rend.gl.GenTexture();
            rend.gl.BindTexture(TextureTarget.Texture2D, testTex);

            uint sx = 2, sy = 2;
            rend.gl.TexImage2D(
                GLEnum.Texture2D,
                0,
                (int)GLEnum.Rgba8,
                sx,
                sy,
                0,
                GLEnum.Rgba,
                GLEnum.UnsignedByte,
                null
            );

            rend.gl.UseProgram(comp.program);

            rend.gl.BindImageTexture(
                0,
                testTex,
                0,
                false,
                0,
                BufferAccessARB.WriteOnly,
                InternalFormat.Rgba8
            );

            comp.dispatch(rend.gl, width, height, 1);

            byte[] data = new byte[sx * sy * 4];
            rend.gl.BindTexture(TextureTarget.Texture2D, testTex);

            fixed (byte* ptr = data)
            {
                rend.gl.GetTexImage(
                    TextureTarget.Texture2D,
                    0,
                    GLEnum.Bgra,
                    GLEnum.UnsignedByte,
                    ptr
                );
            }

            Console.WriteLine($"Pixel 0,0: B={data[0]}, G={data[1]}, R={data[2]}, A={data[3]}");`

the above code is my test code for the shader, I tried to change dispatch sizes to 1, 1, 1, or width, height, 1, or a few different combinations. it works perfectly fine with sx=sy=1 which tells me there is no issues with the compilation, linking or dispatching of the shader. For those curious the shader is:

#version 450
layout(local_size_x = 1, local_size_y = 1, local_size_z = 1) in;
layout(rgba8, binding = 0) uniform image2D imgTex;

void main() {
    imageStore(imgTex, ivec2(0, 0), vec4(1, 0, 0, 1));
}

I have verified as well that there are no errors after pretty much every line of code, gl.GetError prints NoError every time. I am curious if anyone else has had this issue/has a solution.
