Processing 0123, 0124 Java included version
Windows XP SP2
Java version "1.5.0_06"

The display window is sometimes set to 100x100 pixels and ignores the size() in
setup. When this happens smooth() doesn't seem to work either. Running the
sketch again usually fixes the problem.

void setup() {
size(400,400); // // Doesn't matter if I change set this to PD3, JAVA2D, OPENGL
println(width+"x"+height); // will print 400x400 even if the display window is
actually 100x100
smooth();
}

void draw() {
background(0);
rect(0,0,100,100);
}

display window resized to 100x100 pixels instead of 400x400 pixels
