Hello, I have compiled pd 0.47-1 on Xubuntu 16.04.2 and the patch cords that don't show exept if they are in a straight vertical line.
I found a message from Peter Venus saying the same thing happens on a RPI 3 with the OpenGL driver so it is maybe a problem with my crappy video card? (It is an onboard intel card).
