It looks like you're using a love version that's older than 11.5. There were a couple related bugs with miter line joins when drawing close-to-parallel line segments that were fixed in 11.5.

That being said, you might want a different LineJoin mode as well. "none" works even better for me with that scene compared to the default "miter", when running with 11.5.

Oh shoot, where there any drastic changes and i have to change my code or is it just a matter of updating?

What I hear from what slime has said is that you just have to use love.graphics.setLineJoin("none").

11.5 is completely backward compatible with code written for any older 11.x version, it mostly has bugfixes.
