Bug description
With my Video Projector BenQ PJ in fullscreen() in P3Dand in P2D the window is place on the main screen.
In classic mode that's ok.
May be it's due from my VP because this one is old, I don't know. The definition of my VP is 1920x1080
To fix it I use this code :
import java.awt.GraphicsEnvironment;
import java.awt.GraphicsDevice;
import java.awt.Rectangle;
int target_screen = 2;
void setup() {
fullScreen(P3D,target_screen);
secure_screen_place(target_screen);
}
void secure_screen_place(int target) {
GraphicsEnvironment environment = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] devices = environment.getScreenDevices();
Rectangle rect = devices[this.display -1].getDefaultConfiguration().getBounds();
surface.setLocation(0,0);
int x = (int)rect.getX();
int y = (int)rect.getY();
println("repositionnement", x, y);
surface.setLocation(x,y);
}
For an unknown reason it's necessary to set in first the location to zero before move to goal position.

I fix this bug in Processing If you're interested I can push it !!!
But it's more an hack, because It's hard to manage the variable between the static and the non static class PApplet and PSurface
