Linux filters only behave when actually sampling the image in an expected manner?

[micsthepick]

float4 mainImage(VertData v_in) : TARGET
{
    return float4(1.0, 1.0, 1.0, 1.0);
}

the above shader is a MCVE for a filter that doesn't work on linux, and below is a MCVE for a filter that does:

float4 mainImage(VertData v_in) : TARGET
{
    return float4(image.Sample(textureSampler, v_in.uv).xyz, 1);
}

I'd expect both to work fine?

When it is not working, what does it show? Is there an error in the OBS log file?

[micsthepick]

21:00:00.202: glGetAttribLocation: Could not find attribute '_input_attrib1'
21:00:00.202: device_draw (GL) failed

EDIT: as for what it shows: a transparent source the same size.

seeing this with the built in ascii.shader as well.

Update, since I know nothing about the shader language, I tried your change above in the ascii.shader and that seems to fix it on linux. @micsthepick

Also wanted to add my environment

I'm having the same issue with the same error. I can't seem to use variables like v_in.pos.
