That is how it should look.



17:02 < nha> funny because Prf_Jakob seems to think it's related to l=
oops in
the pixel shader...

Looks my analysis was wrong. Since the fragment shader in use is trivial, t=
ho
making it even more trivial makes it work (not using inMinEdge).


#version 450 core

layout (location =3D 0) in vec3 inPosition;
layout (location =3D 0) out vec4 outColor;


void main(void)
{
        outColor =3D vec4(inPosition, 1.0);
}
