P2D-Mode: double Pixels

carlosparadiso

in following code

void setup() {
  size(200, 200, P2D);
  background(255);
}

void draw() {
  point(mouseX, mouseY);  
}

processing draws to points, one at mouseX,mouseY another one at mouseX+1, mouseY-1. Is this a bug in processing or an openGL-bug? Has anyone the same problem? (MacBook Pro, NVIDIA GeForce GT 750M 2048 MB, OS X 10.10.5, Processing 3.0.2)

same on linux.

if you add noSmooth(); the problem disappears. as do ALL the pixels. 8)

size(200, 200);

fixes the problem

Same on windows.

Or almost the same, it's drawing a point at mouseX, mouseY and a point at mouseX-1, mouseY here.

@koogs: no Pixel is interesting, but not the solution ;o)
