That's an odd error. It looks like the graphics driver is reporting the vertex shader's varying output vClp as an attribute input.
I'm making a wild guess your machine is an HP 250 G1 - can I ask what GPU you have in the machine?

Also, do you mind trying out a possible fix? Please try adding the line #version 110 to the top of all the shader source strings in blitter.go?
