There’s a way to do it where you pass one extra vec2 from the vertex shader and use that to determine how much of the pixel is covered by the lines. (This has the effect of thinning the line, so you may want to thicken it to compensate)

Here’s an example of a pair of shaders that do this: https://github.com/paulgb/experiments/tree/master/2021-05-20...
